Brady has needed to make an adjustment for years. He’s been reliant on receivers who can read defenses. The NFL has changed, and it’s more about athleticism now. Brady has brought this up in the past.
In New England, the receivers haven’t been very athletic, and perhaps part of that is Brady/the Patriots fault for not adjusting to the times. All around the league even average to decent QBs are doing just fine.
If Brady goes to Tampa, he’s also leaving behind his New England playbook and philosophy. He’ll need to learn some new terminology, but mostly he’ll be embracing a simplified system.
He’ll be fine. He’s never had weapons as good as TBs except 2007 and maybe some peak Gronk/Edelman years.
