Joe Montana thinks it's a damn shame Tom Brady won't finish his career in New England ... and he's laying the blame for the GOAT's exit at the feet of the Patriots.
"I don’t know what’s going on inside there," Montana said Wednesday, "but somebody made a mistake."
Joe Cool told USA TODAY Sports there's just no way in hell that breakup needed to happen ... saying the Patriots really should have done more to keep their quarterback in the mix.
Of course, Montana doesn't necessarily think Brady's without fault for the dissolution of the relationship .
