‘A great team, the pro football adage says, needs a great quarterback. So much for adages. First off, parity rendered the word “great” in relation to National Football League teams as obsolete as the single-wing formation. “Pretty good” would represent a major step up for most. The Buffalo Bills, who embodied the above bromide through the late 1980s and early ’90s, would settle for “not horrible.” Particularly after their pathetic showing Sunday night in San Francisco. Then you look at the guys throwing the passes. Kurt Warner and Peyton Manning come closest, but even they have turned into interception machines the last few weeks. Fans and general managers alike salivate at the thought of drafting a prototypical quarterback like Manning. But more and more, the top passers take Warner’s more circuitous route to stardom.’
