Tom Brady may never retire. And based on an upcoming episode of “Man In The Arena,” there is one particular loss that is to blame for the GOAT’s seemingly never-ending career.

According to NESN’s Zack, who got an early look at episode 4 of the series that covers the 2007 New England Patriots team that went 16-0 in the regular season, he claims that Brady points to one particular loss in his career that may very well be the reason why he’s still playing today.
