This is a stupid debate ! Neither of them is more important than the other. Together they won 6 SB's. Without Bill, Brady would never have won those many, he might not have even got a starting position in the NFL. considering every team passed on him for 6 rounds ! Without Brady, Bill would have not won 6 SB's, I still think he would have won about 2 but that's it.
If Brady gets trounced the 1st round of the playoffs, then he hasn't accomplished much without Bill either. That would be what he did in NE last year, and that wasn't good enough. If Brady doesn't make it pass the WC, then he will consider the year a failure as we consider this year a failure for the Pats. In that case, it is a draw, they both failed without each other !
As of now, I am interesting in seeing this team's re build and excited about what the future might hold. I am not concerned about what Tampa does. Both Brady and Gronk jumped ship, why are some fans so obsessed with what they are doing ? The fans who want to blame Bill for everything may as well start rooting for another team, they don't have an allegiance to the Patriots at all, they were more Brady fans then fans of the team . My focus is on seeing the Pats build a team that can compete again for the AFC East crown and the AFC in general .
