I will echo some of the other comments. A solid #2, but not much upside beyond that. Buffalo had a great run back in the 90's, but I have no faith in the current organization to build much of an offense around Lynch. Much like when McGahee and Henry were there, I think he'll continue to have a low ypc around 4.0, 1200~1400 total yds and 6~8 TD's.
You obviously dont watch Bills games. In the past 15 years or so (since their glory days of the ealry 90s), they havent had anything consistent. No constent OL, QB, RB, coaching... Nothing. Now, they have a HC that has a plan, and is starting to show more,
they have an OL that is one of the better ones in the league, they have qhat appears to be a competant QB, and obviously they drafted ML early to be their starting RB for many years. The biggest problem with this team is the WR position. Evans is a stud, but no one else is half as good. They need to have a good draft this year, and one of their 1st 2 picks has to be WR. They need someone that can make teams respect the passing game, so that the OL can open up more and bigger holes. I think all these things happen this year, and Lynch improves on a pretty good rookie year. He will slightly improve this year, and I think this team takes HUGE strides next year. He might be expensive now, but in a dynasty, me thinks you better get him now before he becomes untradeable.
