Unlikely they are four failed qbs. If you are waiting for a can't miss, perfect qb, you are going to wait a long, long time. And even then, unless you are picking 1 overall, you will wait forever. Historically, top of the draft has a 50% hit rate for qb. It's considerably lower later on. This is potentially a very strong qb draft. Bills set themselves up to take a shot and it's time to do so. Radical pessimism about the position is a prescription for continual irrelevancy.
