I don't know what's going on inside there, but somebody made a mistake," Montana told Jarrett Bell of USA TODAY Sports, regarding Brady's free-agent move to Tampa Bay. "I think when you look at the whole situation, you try to figure out how you want to get away from things that are there. I had a different story, where they had made a decision. He, obviously, they never would have gotten rid of. I still don't understand how New England let him get away. I don't understand that"
"I don't know exactly what he's looking for, but my understanding was that he's just looking for more control of the offense. But I don't know. I haven't had a long conversation with him; I talked to him a little bit at the Super Bowl, but not enough time to really get in-depth."
