Dorsey is the best defensive player in the draft. I think he'd fit awfully well with the Raiders. Besides, many mocks have Long going No. 1 overall to Miami to be their 3-4 DE (with the signing of Parcells).
Rey Maualuga is apparently staying in school.
Anyway, for the Rams:
DE Vernon Gholston, Ohio St.
DE Chris Long, Virginia
DT Glenn Dorsey, LSU
Those are the only three guys, who fill needs (kind of on Dorsey) for the Rams, who are worthy of the No. 2 pick. The Rams are actually in a good position, as they'll have 3-4 teams calling and talking trade (so they can get McFadden).
As for the OT debate, I've actually got Ryan Clady (who just declared today) rated above Jake Long. I just see him as a better prospect and NFL LT than Clady. With a solid off-season, I could see him going as high as No. 5 (if the Chiefs pick there).
