The first thing that you notice about Trey Lealaimatafao is that he's squat. Many times the Longhorns have pursued defensive tackles in the past who are longer athletes that can add weight to bulk up. That's not the case here. If Lealaimatafao adds any weight at the college level, it won't be much. He's incredibly blockish, with Popeye arms and a thick lower base.
Of course that, combined with his high overall strength level and good quickness off the ball, makes him difficult to move at the point of attack. Several times at practice, I saw him attack waves of blockers and hold the point, a good attribute for a guy who could often see himself double-teamed at the next level.
Warren utilizes a gap-control defense, meaning that Lealaimatafao is typically set up right in the gap between two people. As I said above, he has good quickness, though it's important to note that he's not as elite in that category as a guy like Alex Norman was coming out. He's also not an elite athlete in terms of overall movement as Hassan Ridgeway. But what Lealaimatafao lacks there — and again, it's not necessarily that he lacks it, he's just not elite there — he makes up for with high-level strength and a fantastic motor.
He claims an almost 400-pound bench press, and though he didn't test in the area, his squat will probably measure out in the 500-plus pound range. When added to his aggressiveness level, you have a guy who is a nightmare in goal-line situations, when pad level and strength count for so much. In fact, Lealaimatafao made tackles on each of the first three plays Warren ran in a goal-line situation. On the fourth, all he did was move two guys two yards deep into the backfield, essentially blowing up the play. And on the drill's final rep, he fought off multiple players to pull down the back in a pile. None of the reps went for touchdowns while he was in the game. He arrives at the ball-carrier angry and tackles with plenty of physical force.
Lealaimatafao isn't your typical Texas defensive tackle — unless your name is Desmond Jackson — but that doesn't mean that he won't be effective at the next level. His low center of gravity, strength and ability to anchor make him a valuable commodity, while his power and motor are projectable talents.
