Mack is currently rated as a Scout.com five-star prospect, the No. 2 defensive tackle nationally and the No. 3 prospect in the country regardless of position.
"He is so big and strong," Scout.com National Analyst Greg Powers informed. "He moves extremely well on his first step and can penetrate in to the backfield at times with cat-like quickness, which is quite an attribute for a player easily over 300 pounds."
"He runs well and is good in pursuit. He plays high at times, but is a difference maker when staying low. Makes the 'wow' play at times. He can get in the gap and blow plays up. Still extremely raw with a ton of upside for development. A strong tackler."
Mack had been leaning to A&M for awhile, but had hit the pause button on making his commitment on a couple of different occasions.
"Because I feel like that's the right place," Mack answered calmly when asked the reasoning behind wanting to commit early.
It also meant something to Mack that the Aggies were first to the table with an offer.
"With A&M, it's because they were my first offer. I love the staff and the SEC in Texas.
As a sophomore Mack collected 62 tackles, 15 tackles for a loss and six sacks, earning 16-3A Defensive Newcomer of the Year honors.
