I know LT is important, but if you think about it, the shortest distance to a QB is where ? A: through the middle.
Cowboys fans have been spoiled by exceptional guard play. From Ralph Neely and Tom Niland in the early 70's, to Herbert Scott and Tom Rafferty in the late 70's, and early 80's, to Nate Newton, Kevin Gogan, and Larry Allen in the 90's, we've always had people who can take care of the middle. If you don't think that's too important, take a look at what happened this past season when Kozier, who's not exactly one of the best ever, but a solid player, went down.
Cowboys shouldn't move Davis to LT. He does not play up to his potential in space. However, if you leave him at guard, he could become one of the great ones, like Larry. Maybe not as good as Larry, but within the same neighborhood. Don't fix something that's not broken.
This draft is very, very, VERY loaded with tackles. The Cowboys could get one in the 2nd or 3rd round and just develop him. It's a tall order for a team who hasn't developed an offensive tackle since 1998, but they have to keep on trying.
