I'm assuming you're talking about Will Campbell. He ran a 4.98. Believe it or not there were four others who ran an even faster time, with Georgia's Jared Wilson leading them all by clocking in at an insane 4.84. Wilson also tied for second in the 10 yard split with a 1.72 time. Most coaching staffs tend to lean a bit more on the splits mainly because how many times does an offensive lineman need to run 40 yards during a game.
Wilson is a center. I think I'd prefer they just go sign this Dalman guy.
One because experience is nice at the center position. (Yes, Coleman Shelton was out-talented and it showed a lot last season, but at least he had some intangibles that carried him to perform respectably at times. Just apply those intangibles to an actually talented player and Voila.)
And two because we don't know if we'll necessarily be able to draft Wilson, so just take the bird in the hand and pay the proven FA that is available. Also Dalman is still a good age at 26 to sign longer-term.
