You CAN have that if you build a team to be a one-hit wonder. You really can't have that if you are trying to be at or near the top every year, with no "reset" or "cap hell" years mixed in. Nearly every year, the team had a 'weakness' that they decide to roll with, in the interests of not strengthening this year at the cost of really undermining next year.The following year the team fields one of the best defenses in franchise history, and it absolutely carries the team, and Brady is pissed because now he doesn't have enough offensive weapons. So it gets back to a question I asked during last year....if you were Brady, knowing that you can't have EVERYTHING you want, would you rather have a great set of weapons around you but a mediocre defense (which is what sunk them in SB 52), or a great defense and mediocre offensive weapons (which allowed them to win SB 53 but which clearly frustrated him in 2019)?
It seemed like as his career with NE wound down, Brady was only going to be happy with both great offensive talent around him AND a great defense. Well Tom...I mean...come on man.

At 43, Brady isn't very concerned about the post-Brady health of a franchise in teh abstract. But I also think he truly is very fond of Kraft and BB and he doesn't want to murder the Patriots' future (nor will they allow him to do it). But he does want a "perfect" team, and knows he has to go elsewhere to get it in the short term, because Kraft/BB wont do that. If there is a "he was never coming back" angle, that's it. Not some dissatisfaction with Kraft or BB.
