Someone said in this thread or a similar one.... something like: The gap between most NFL players isn't that large. It all boils down to preparation, coaching, and risk management/aversion. That is the Patriots' biggest 'secret' and why they always think it is a good idea to make 20 trades at the draft for quantity.
The Bills still trade up, have foolishly spent up to the cap, constantly shoot themselves in the foot with Personal Fouls and silliness, shoot themselves in the foot with "communication issues", getting offensive plays in late, and depending on Rex Ryan throwing the challenge flag based on what angles the scoreboard shows and the player lobbying in his ear. Not to mention the constant and endless pattern of leaks and distractions coming from OBD on every subject.
