No way will the Bills roster become a trend, for two reasons, neither of them related to how effective we'll actually be.
The first reason is that if we win many will think our QB is good regardless of the reality. Lets just say we win the Superbowl with EJ or Tyrod Taylor (I'm a little skeptical that anyone could think Meh is elite) there will immediately be the perception that they are good and as soon as their contracts are up (which is almost immediately) you would have to shell out big money to keep them or they will walk. Even if you don't need a good QB to win I doubt you can have a bad one or a new one consistently. If we lose our QB and they do poorly elsewhere it wouldn't start a trend, there's been plenty of QBs with one or two good seasons and then nothing.
As for the second reason. I think it's going to be really tough to keep the level of talent we have on our roster even if we completely ignore the most important position. That being said as soon as what we're doing is seen as a viable option to win with it will become more expensive to get all these great players and it will stop being viable, not to mention the problems you'll have with available talent. We have two of the best full backs out there, not to mention all the other great players.
