What does Moore's illness mean? For one, it means that those wanting to see more of true freshman defensive tackle Malcom Brown — arguably the top signee in the Longhorns' 2012 class — may get their wish. With the tempo Oklahoma State plays with, it's tough to get by with just three defensive tackles, and so Brown, who might have seen more action this week anyway, may have to take on a bigger role.
But also, from a skill set standpoint, the Longhorns lose arguably their top run-stuffer up the middle, and somebody who seemed to come on well against Ole Miss. The Longhorns might be at their best when they pair Moore with the quickness and tenacity of Desmond Jackson, and at least this week, that option isn't available to them. Add that to the injury of Jordan Hicks, and the Longhorns are out two of their top in-the-box defenders.
Unlike with Hicks, because of the depth the Longhorns have at tackle, there isn't a massive drop-off from Moore to the next guy (or guys) up. So the real issue here is depth. Will the Longhorns have enough tackles to play in this track meet? Will Brown be able to handle more of a role if he gets one? Those are all questions that Texas, somewhat unexpectedly, will have to answer this week.
