Tampa Bay quarterback Tom Brady is retiring after 22 years in the NFL, ESPN’s Adam Schefter and Jeff Darlington reported.

Brady, the most successful quarterback in NFL history, has won seven Super Bowls — six with the New England Patriots and one with the Tampa Bay Buccaneers — and won five Super Bowl MVPs and three NFL MVP trophies. He went to 15 Pro Bowls and was an All Pro in each of his MVP seasons.

“I understand the advanced speculation about Tom’s future,” Brady’s agent, Don Yee, told ESPN’s Schefter in a statement. “Without getting into the accuracy or inaccuracy of what’s being reported, Tom will be the only person to express his plans with complete accuracy. He knows the realities of the football business and planning calendar as well as anybody, so that should be soon.”

Brady’s last season came to an end with a loss to the Los Angeles Rams in the divisional round of the playoffs. In true Brady fashion, the quarterback led his team back from a 27-3 deficit, only to lose 30-27 on a field goal by the Rams as time expired.

Even as the oldest player in the league, Brady had one his best seasons in his swan song. He led the league in passing yards (5,316) and passing touchdowns (43).

Brady, 44, played two seasons with the Buccaneers after leaving New England in 2020. In his first season in Tampa Bay, he led the Bucs to their first Super Bowl win since 2003.

He holds virtually every career record by a quarterback, including most passing yards (84,520), pass completions (7,263) and passing touchdowns (624).

While Brady himself has yet to announce the move, his company, TB12 Sports, tweeted the star’s accomplishments and wrote “Thank you for it all, @TomBrady.” The account later deleted the tweet.

Brady has delved into several off-field endeavors in recent years, including his TB12 Sports, a health and wellness company, and the Brady Brand clothing line, which he launched earlier this month and will be sold in Nordstrom stores.

He told ABC’s “Good Morning America” that he has been “very involved” in the clothing line.

“I’ve always kind of, you know, loved fashion and apparel, and I wanted to be as hands-on as possible,” he said.

Following the 2021-22 season, he had said he would talk with his family about whether he wanted to return for another season. Brady is married to supermodel Gisele Bundchen, with whom he has two children. He also has a son with actress Bridget Moynahan.

Brady was far from a highly touted prospect as a sixth-round pick out of Michigan by the Patriots in the 2000 NFL draft. But a hit by New York Jets linebacker Mo Lewis on Patriots starting quarterback Drew Bledsoe in Week 2 of the 2001 season launched Brady into stardom in his second season. He ended up starting 14 games, leading the team to an 11-3 record and an upset win against the St. Louis Rams in the Super Bowl.

He won two more Super Bowls in the next three seasons, establishing himself as a star and the Patriots as a dynasty led by head coach Bill Belichick.

Brady also won Super Bowls with the Patriots in 2015, 2017 and 2019. He’s the only player to win Super Bowls in three different decades.

For years, Brady’s only kryptonite appeared to be the New York Giants and their quarterback, Eli Manning. The Giants defeated Brady’s Patriots in 2008 and 2012. New England had entered the Super Bowl in 2008 with an undefeated record and was looking to become the first team with an unblemished record since the 1972 Miami Dolphins.

Brady’s only other loss in a Super Bowl came in 2018 against the Philadelphia Eagles — despite throwing for over 500 yards and three touchdowns.

His career was marked by a few controversies, including the so-called “Deflategate” scandal following the Patriots’ 2014-15 AFC title game win over the Indianapolis Colts. The team was accused of intentionally underinflating footballs, which would make them easier to grip and catch. An investigation by the league, which found Brady had even destroyed his cellphone, ended with Brady being suspended for the first four games of the 2015-16 season. The team was also fined $1 million and forfeited a first-round pick the following draft.

The Patriots were also accused of spying on opposing teams’ coaches during the 2007 season, videotaping signals being sent to players on field. Belichcik was fined $500,000, the team was fined $250,000 and the team lost its first-round pick in the 2008 NFL draft.

The cheating allegations have had little impact on Brady’s legacy, especially as he continued to lead teams to Super Bowl victories — even after leaving the confines of Belichick’s secretive leadership in New England.

The reaction to Brady’s retirement was swift. Former Patriots teammate Julian Edelman tweeted, “Thanks for the memories, babe.”

Several of his Tampa Bay teammates also tweeted about the news. Wide receiver Chris Godwin tweeted, “The best ever. Congratulations bro @TomBrady grateful to have gotten to share the field with you!” Bucs linebacker Devin White shared, “Congrats to the greatest QB to ever lace em up on a helluva career.” Wide receiver Cyril Grayson wrote, “Happy Retirement! THANK YOU FOR ALL THE GAME!”

Millions of Americans are under winter weather alerts Saturday as a nor’easter slams the Northeast.

Whiteout conditions persist as the winter storm makes its way toward the New England coast.

Snow has been falling at a rate of 2 to 4 inches per hour in Massachusetts, Gov. Charlie Baker said during a Saturday evening press briefing. The winter storm is “delivering as expected,” he said, with strong winds and large amounts of snow hitting the state’s eastern, southeastern and coastal communities the hardest.

Parts of New Jersey, including Atlantic City, saw snowfall rates upward of 2 inches per hour, while eastern Connecticut saw as much as 3 inches per hour.

In addition to the snowfall, strong wind gusts of 60 to 70 mph have been reported along the Northeast coastline.

States of emergency were in effect in several states as they braced for the worst of the storm system Saturday afternoon.

Whipping winds, treacherous travel, potential power outages and frigid temperatures are all concerns associated with the winter nor’easter. Over 100,000 customers are without power in Massachusetts, and over 3,550 flights have been canceled within, into, and out of the U.S. Saturday, according to Flightaware.

In Connecticut, airports are “down at this point,” Gov. Ned Lamont said during a briefing midday Saturday. Metro-North is running on limited hourly service, and Amtrak is not operating, officials said.

Snow totals, treacherous conditions

By Saturday afternoon, over a foot of snow had so far fallen along the Northeast coast, with parts of New Jersey and Long Island reporting over 18 inches.

Additional snow accumulations of 3 to 6 inches are forecast from eastern Long Island up into central New England, while another 6 to 12 inches is expected along the New England coast.

Parts of Connecticut to Maine may see up to 18 to 24 inches of snow total, with the possibility of up to 24 inches near Boston Metro — a potential record breaker. For the city of Boston, the most snowfall in one day in January on record is 22.1 inches — Jan. 27, 2015 — and the most snowfall in one day on record overall is 23.6 inches, which happened Feb. 17, 2003.

Southeastern Massachusetts could get about 30 inches of snow, the governor said.

Coastal New Jersey; Suffolk County, New York; Rhode Island and coastal Massachusetts experienced whiteout conditions — persistent heavy snow and gusty winds.

The Interstate 95 corridor north of New York City toward Boston and Portland, Maine, saw whipping wind gusts of 45 mph to 70 mph.

Below-zero wind chills

Parts of the Great Lakes and New England likely will experience bitterly cold temperatures with wind chills near 25 below zero.

The Northeast will feel frigid Saturday night as wind chills plunge to 2 and 5 below zero in New York City and Boston, respectively.

Cold weather is even heading south to Florida with temperatures dipping into the upper 20s by early Sunday. Wind chill alerts have been posted for cities including Miami, Naples and West Palm Beach. Freeze warnings were in effect for much of Florida Saturday night.

Coastal concerns

There are coastal concerns about storm surge and tidal influence especially along the coastal towns in Suffolk County, New York, which could see 4- to 8-foot-high waves during high tide Saturday night and into Sunday.

Boston may also get battered with largest wave swells at 15 to 20 feet.

Beach erosion, localized flooding and property damage are all possible in these areas with the storm and high tides.

Some coastal communities in Massachusetts are experiencing minor to moderate flooding, Lt. Gov. Karyn Polito told reporters Saturday. Nantucket saw high floodwater, with “significant flooding” downtown, officials warned.

However, there is one silver lining to this winter storm: The storm system remained easterly, meaning less heavy snow and weather-related snarls for states west of I-95.

National Transportation Safety Board investigators spent Saturday on scene investigating the bridge that collapsed in Pittsburgh one day earlier.

Three people were hospitalized but no one was killed when the Fern Hollow Bridge collapsed before rush hour Friday. Five cars and a Port Authority bus were on the bridge when the bridge collapsed.

NTSB chairwoman Jennifer Homendy told reporters Saturday she expects the investigation to be “long” and “technical.”

“Our mission here is to determine how this collapse happened, why it happened — to prevent it from happening again,” she said.

Investigators used a drone to map the scene and did an initial inspection of the structure and the legs under the deck of the bridge, Homendy said.

“We want to see how the structure came to rest and we’re looking for things like signs of corrosion, signs of fatigue cracking,” she said.

In addition to analyzing the wreckage at the scene, Homendy said her investigators will look at any video evidence and is looking to obtain any video taken from cameras inside the bus that was on the bridge at the time of the collapse.

Homendy said they were able to obtain video from a local business that determined the time of the accident was approximately 6:40 a.m. She called on anyone with additional video to contact them to aid in the investigation.

“We’re going to put this bridge under a microscope,” Homendy said. “We’re going to look at the entire history of this bridge — from the design, construction, maintenance repair, all work up until the day of the collapse.”

Investigators will also look at the inspection frequency of the bridge, as well as federal and state procedure loads on the bridge, she said.

Homendy expects a preliminary report to be released in 10 days. While a cause of the collapse cannot be determined yet, she said the incident should “serve as a call to action.”

“Of the 618,456 bridges in the United States, 47.7% are rated fair, 7.3% are rated poor,” Homendy said. “Of the 22,965 bridges in Pennsylvania, 52.8% are rated fair and 14.6% are rated poor. So, this is a call to action because we have aging transportation infrastructure.”

When asked what it was like to see the damage up close, Homendy said it’s fortunate no one died.

“Injuries are very serious, but when I looked in the position of the bus, and the position of the vehicles, I’m really thankful that no one lost their life in this collapse,” she said.
