Actually, what I think Sullivan meant to say was that the chances of going to a SB are low unless you have a QB who is playing in a top-flight MANNER.
A mid-flight performer is NOT going to get the job done.
DB shows no signs of ever performing like a top QB unless it's against poor competition.
Therefore, try the OTHER guy.
We don't know what level JP will be able to perform.
Sadly, we know the answer with Drew. The Bills will move on, IMO.
