Just being honest, the Bills have a better QB depending on whether Matt Moore or a HEALTHY David Garrard wins the job, they have better RBs, better WRs, better DL and better DBs.
Miami has better TEs, a better OL and better LBs. Yet even those edges are tenuous because Scott Chandler had a very Anthony Fasano-like year, their OL for all its supposedly being less talented than ours actually outperformed our OL in 2011, and the margin on the linebackers is not wide because of the presence of Nick Barnett.
So yeah I think I'd forecast that team better right now, especially as everyone in Buffalo returns in the same system whereas the Dolphins are hitting the reset button on both their offense and defense.
As for the Jets, well if you want to be considered better than them we ought to try actually BEING better than them because as much as we chide their sinking ship they win more games than we do and at this very moment they have a more talented roster, not to mention a much more proven defensive staff.
So what we're 4th in the division right now. The Bills and Jets are sinking, they're just fighting the good fight. The Bills will continue to pound their head into a wall until they find a better QB and the Jets are the same way, except they may fall harder because they're more likely to convince themselves they have a QB between Sanchez and Tebow. If Miami picked the right QB then they should eclipse both teams in due time.
