Not a bad mock, nodnarb.
2. Jones is enough of an intriguing pick that it wouldn't bother me to see them draft him, especially if they can do more via trade and free agency to bolster the OL depth.
3. Castillo and Hawthorne would also be nice picks, but I fully expect Castillo to be gone by our 2nd round pick, as some have him rated as high or higher than Travis Johnson of FSU. Hawthorne more than likely will be gone by the 55th pick as well, but if he's around in the 3rd round, by all means take him, TD! Terry in the 3rd? Maybe. He wouldn't be a bad pick at all in round 3. It's not as much of a long shot as Hawthorne and Castillo (Terry being available in the 3rd), but it's still not certain at all.
4. Bartell in the 4th? I doubt it. He's moving up most teams' draft boards, bad news for any team (like the Bills) who could use a big, fast, physical corner. I sure would love for him to be there in the 4th, but the way things have been going recently, I wouldn't count on it.
5. Sproles? I dunno. I like Ryan Moats of La Tech more, but again, will Moats be around in the 5th? Who knows? Even though his workouts have been very good, he doesn't seem to be moving up the draft boards as of late.
6. Reyes is okay, and I guess the Syracuse connection would make him a favorite, but I'd rather have a power back as a backup, especially since the Bills seem fine with Shaud Williams as their speed backup RB. A good power RB that might be around in the 6th is Louisville's Lionel Gates. He's got good size and runs well between the tackles. I would rather see him drafted by the Bills than Reyes.
7. LeFors? If UConn's Dan Orlovsky is gone by then (probably), this wouldn't be such a bad pick.
As far as the RBs go, I wouldn't go after RBs in successive rounds. I'd hope we'd go after at least one interior OL, hopefully a center. Use one of those picks on the best available center, like Jason Brown (doubtful in the 5th/6th, but one never knows for sure), Junius Coston, Vince Carter, or a guy who was impressive in workouts, Rob Hunt of North Dakota State.
