Very simply…. He asked the Patriots to give him a longterm contract. They refused. He then agreed to sign a short term one and negotiated a no strings attached free agency after.
The ball was in the Pats court. Brady gave them every opportunity to ensure he stay. That was their chance to secure him. You don’t get to complain after you passed on that opportunity that he started talking to other people about a future you weren’t interested in locking down when you were the only suitor.
This jilted fan stuff. If you are upset, be mad at the team. The reason Brady isn’t here is because he wasn’t signed longterm when he was asking. Not the Dolphins when he was on his way to free agency.
This isn’t even like Parcells where the team was left high and dry suddenly and embarrassingly. There’s only one reason a guy negotiated a no strings attached free agency in his contract. Pats gave it to him so they didn’t need to commit
