Hall of Fame gunslinger Joe Montana spoke at length about the split between the New England Patriots and their iconic quarterback Tom Brady. The two parted ways last week when Brady announced via Instagram that he would not be returning to the team.

Brady quickly pivoted and chose to sign with the Tampa Bay Buccaneers—the team that would give him the most weapons to work with after a 2019 season without any true high-caliber targets.

Montana, who spent most of his years with the San Francisco 49ers before playing his last two seasons with the Kansas City Chiefs, gave his honest take on this broken marriage:

“I don’t know what’s going on inside there, but somebody made a mistake,” Montana told Jarrett Bell of USA TODAY Sports.

“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.”

Brady had taken pay cuts throughout his career to allow the Patriots to arm him with sound weapons. Besides the signing of Randy Moss, the Pats didn't haul in any elite-level free agent—unless counting the re-signing of Rob Gronkowski.

There are plenty of rumors about a pay disagreement, considering Brady feels he can play for several more years. The Bucs signed him for two years and $50 million, guaranteeing all of it upon signing.
