On multiple occasions Tom Brady has stated his intent to play in the NFL until he's in his mid-40s. He is currently 40. That would lead you to believe he still has a few years left. 

However, for those seeking out confirmation, on Monday, Brady's agent (Don Yee) confirmed that the backwards aging New England quarterback would be returning for this upcoming season.

"Tom's intentions have not changed," Yee said, according to one of Adam Schefter's less impressive scoops. "He's consistently said he'll play beyond this contract and into his mid-40s, or until he feels he isn't playing at a championship level. I understand the constant speculation, but this is one point he's been firm about."

Yee went on to detail Brady's legendary preparation by saying that the five-time Super Bowl champ is still putting in work like a madman. "He customizes his preparation to each season in order to maximize his performance," said Yee. "His training methods are always evolving and getting better. The year he missed the first four games -- that month of training on his own was particularly efficient."

Schefter went on to report that, last week, a "source" told him he thought Brady's chance of a 2018 return was "75 percent." So, whatever, I guess for those who are skeptical about Tom's claims to play until his mid-40s, you got some verification. Until he starts to actually look rag armed (see: Peyton Manning's last season), I probably wouldn't worry a whole lot about this.
