I'll tell you this much: Scouts Inc. (at least on the website on ESPN to follow the draft live) had Maybin as the third rated player in the entire draft. Like a 97 grade on him. I was using ESPN's follow the draft website, and they had him higher than a lot of guys on their draft board, anyways.
I love the guy's attitude, he's a good interview, and appears to be happy to be in Buffalo, but he looks more like a 3-4 OLB than a 4-3 DE.
