Tom Brady on Retirement: 'When I Suck, I'll Retire'

Some people don't know when to call it quits, but New England Patriots quarterback Tom Brady knows exactly when he will retire—sort of.

The 37-year-old isn't giving an exact age or date, but he let everyone know that he isn't going to just hang around and collect a paycheck.

The Patriots signal-caller talked about a number of things on WEEI 93.7 FM's The Dennis & Callahan Morning Show on Tuesday. Among the topics: retirement.

"When I suck, I'll retire," Brady said. "I don't plan on sucking for a long time."

Check out his interview, with the retirement talk starting around the 11:50 mark:

Brady said that while laughing, but the three-time Super Bowl champion means it. Last year, he told Men's Health that he'd love to play until he's in his 50s.

"If I think I can do it, then I probably will," he said.

Who knows when the day will come that Brady "sucks," but it sounds like he is willing to walk away when it does.
