I hear you, and I won't say I'm an expert, but is it that complicated? Is it something any qualified OC could develop with the type of personnel that the Bills have? I like Daboll and think he's done a great job, I just think that there shouldn't be much to worry about in replacing him outside the organization. This is a top job that the best OC's would love to have. The Bills will have their pick of the litter, hire the best guy. If they think it's Dorsey, cool, if outside the org, I'm good with that as well.
Maybe simple is the wrong word, but is it so unique that no other OC could adapt to this personnel and have similar success? And with a running game perhaps?
