He fits the profile of a Cowboys lineman, at 6-9 340 and he's only 23 (per ESPN), and he is likely to receive a first round tender per ESPN.
Also, this is what the scouting section of the ESPN player profiler says,
Gaither is a young, ascending player and the Ravens' starting left tackle. He has tremendous size, particularly with his extreme height and overall length, to man the blind side. However, there are times when his high center of gravity is used against Gaither. Gaither remains a work in progress but is a punishing finisher in Baltimore's power blocking scheme. As he gains experience, his hand placement and understanding of his opponent will improve.
Now, considering that it seems likely Russell Okung, Bryan Bulaga, Bruce Campbell, Anthony Davis, Trent Williams, and Mike Iupati will be gone by the time we pick I think it makes some sense to look into this option. We know he can play already, so there's less risk. I think that if the Cowboys scouting department would grade him higher than any lineman we could get in round 1, we should at least consider making him an offer.
Also, we would have a legitimate shot at signing him away seeing as the Ravens have Michael Oher who they know can play the left side and so might decide to part with him for a first rounder.
Another thing to consider is our first rounder may very well have only second round value (depending on how many first round grades our scouts assign) and thus our pick is more like a high second rounder.
My only reservation, is we can't know who would fall to us at 27 right now, and I don't like trading draft picks for players. (Every time I think of the Joey Galloway or Roy Williams trades I get very angry, all the young talent we gave up for them).
However, this may be the best shot we have at shoring up our line and considering Jerry's comments concerning whether or not we can get another good year from Flo, this should be looked into in my opinion. Your thoughts?
