The release of the video, called āThe Legend of Tom Brady,ā was timed for the big game.
āI witnessed Tom Brady throw a football all the way across the Boston Harbor. I was there ā I saw it with my own two eyes,ā says a Bostonian at the videoās start.
āEvery kid in Dorchester legally has to be named Tom or Brady. The girls, too,ā says a woman in a bar.
Brady, 39, led the New England Patriots to a Super Bowl victory Sunday, erasing a 25-point deficit.
The quarterback was originally signed by Under Armour in 2010. His wife, model Gisele Bundchen, is also an endorser for the Baltimore-based apparel, footwear and fitness technology company.
āThe film is a montage of New Englandās biggest fans speaking to Brady's many incredible exploits,ā says a news release promoting the tongue-in-cheek video, which was accessible through Facebook, Twitter and YouTube.
Under Armour has been selling Brady-endorsed sleepwear. He was previously part of the brand's āRule Yourselfā campaign along with golfer Jordan Spieth, NBA star Stephen Curry and ballet dancer Misty Copeland.
Another Under Armour star ā Carolina Panthers quarterback Cam Newton ā was featured in a Super Bowl commercial on Sunday playing footall with kids.
The ad was for Buick. But Under Armour says it supplied products, and the companyās logo appears prominently during the spot.
