Honest question: After DeCastro at guard, the other pure guards are considered 2nd rounders at best. Glenn is only a 1st round consideration because he may make it as a right tackle. At tackle, there are 3-4 players who may get into round one after Kalil and Reif, and others rated fairly high; with tackles, if there is doubt that they can cut it on the left side, they tend to drop in value as RTs or guys like Gallery who end up as guards for years. So....after DeCastro in round one, if we look at a guard instead of a center, why are we intent on looking at the lesser guards in rounds 2-3 instead of some of the tackles in rounds 2-3? When I check out Kiper, Ourlads, and others, there seem to be around a dozen tackles with potential to become starters at tackle, and their only question marks seem to make them ideal candidates to move inside and play multiple positions. Are the lesser guards, who also have questions around their flexibility or feet or pass protection, really better candidates for us than those tackles who are there at pick 45? The Cowboys have a long history of finding starting guards among former tackles who were better linemen to begin with.
