Good post, but I disagree. Defense wins championships, and that's been the consistent Super Bowl formula for decades. New England wins because Belichick is the best defensive mind in football history. There are other factors but that is the most important one.
We should imitate New England (and Baltimore, Tampa Bay, and other champions with great defenses) by building the best D we can. When the Bills win the Bowl, it'll be with the best defense in football, a D that makes plays especially in critical moments.
