I'm actually a Bills fan and I am baffled by this. It does look like they are going for a dynamic offense. We were courting Lavaraneus Coles for a while. Marshawn Lynch is very, very good and is held back by the lack of a passing attack and a crap o line. I'd highly recommend to draft Marshawn in your fantasy league if he's not suspended for the first 4 games for the gun possession thing.
The problem is that we have an offensive line that is pretty lame and a QB that has never come close to a good game in bad weather or against someone in our division. He has shown signs and will be more comfortable in our offensive scheme next year. (I can't count the number of times I have seen this excuse for average qb's) Our former pro bowler, Peters, came in after a holdout and was out of shape and never really caught up. We need to address O Line and D Line in the draft.
