Been following this since the beginning. for people like susweel Matt Miller is the founder of New Era Scouting which has been featured on NFLN and in various major newspapers. He's one of the top writers on Bleacher Report. He isn't one of the average fans writing on there. It's probably as legit if not better than the ESPN or NFLN lists.
Anyways, really haven't found anything to disagree with so far for the rankings. I wish he would have done NT and DT's separate though. I guess I would still put Sopoaga at 6 or 7 of the 15 or so NTs so 1/2 way still evens out to close to 30/64 anyways. Sopoaga doesn't have much pass rush ability but it's not his job. Still there are some NTs that can rush the passer so I can see why he is behind them. He's near tops in run stopping but is average at pass rushing but again it's not his job.
