Who are the best OGs OTs, DLs and LBs to take in Rounds 4-6?

What do you think about this guy:

" Kirk Barton, OT, Ohio State
Height: 6-5. Weight: 311.
Projected 40 Time: 5.08.
Combine 40 Time: Did not run.
Pro Day 40 Time: 4.95.
Arm: 33 1/4. Benchx225: 34.
Projected Round: 3-4.
Kirk Barton expelled all concerns about a lingering knee injury by looking very impressive in the drills at his Pro Day. He also ran a 4.95 and benched 225 pounds 34 times."

 

Here's another guy I haven't heard a lot about that looks interesting:

" Drew Miller, C/G, Florida
Height: 6-5. Weight: 297.
Projected 40 Time: 5.07.
Pro Day 40 Time: 5.03.
Benchx225: 34.
Projected Round: 5-6.
Drew Miller wasn't invited to the combine (and I have no idea why), but he had a solid Pro Day, posting solid numbers in the bench, 40, vertical (30 inches) and broad jump (9-3). That should cement his status as a middle-round interior line prospect.

Started as an offensive tackle, played guard in 2006 and slated to move to center in 2007. His versatility will be enticing for some NFL teams. "

 

Maybe this guy's a workout wonder. Maybe not.

What do you know about it?

" Brian Stamper, OT, Vanderbilt
Height: 6-4. Weight: 300.
Projected 40 Time: 5.19.
Pro Day 40 Time: .
Benchx225: 38.
Projected Round: 6-7.
You have to like this guy. Brian Stamper put up 38 reps of 225 pounds despite suffering a hamstring cramp when he was on his 20th lift. Instead of stopping, Stamper continued to bench with his legs straight up in the air. After he was finished, Stamper was disappointed, stating that his goal was around 45 reps. "

 

All these guys in these Sat. am comments are from Walterfootball.com, which a friend of mine clued me in on the other day.

" Brandon Keith, Northern Iowa
Height: 6-5. Weight: 349.
Projected 40 Time: 5.29.
Combine 40 Time: 5.23.
Pro Day 40 Time: 4.98.
Benchx225: 31.
Projected Round: 5. I know 40 times for offensive linemen is meaningless, but a 4.98 from a 343-pound monster? Wow. "

What about this guy, huh?
