He excels for the Gladewater (Tex.) High baseball team and basketball team, as well as for its football team as a standout defensive tackle.
Though accomplished elsewhere, including as a pitcher, football is where Mack projects best at this point.
He's been clocked sub-4.9 seconds in the 40-yard dash, and had a great 2012 season in registering 16 tackles for loss including six sacks as just a sophomore.
On Friday, however, he became a national recruit as Alabama threw its hat into the mix.
"It felt great," Mack said of his newest extension. "It was a real honor to have an offer to such a top tier school."
While many regional schools offering put him on the map as a class of 2015 talent to monitor, he admitted the offer from the national champs is something he didn't see coming.
"I got a phone call from coach [Billy] Napier," he said Friday. "I didn't expect it."
The defensive tackle prospect has visited the Longhorns and Aggies thus far, and has made it no secret that the newest SEC team is ahead of the pack at this point.
However, Alabama's interest in him now has him contemplating holding off of a commitment to any program for now.
"They stack up really well," he admitted. "They are at the top with A&M."
Napier explained what he liked about the talented prospect earlier in the day.
Said Mack, "He said he had been hearing a lot about me and he liked my film."
Alabama encouraged the sophomore to make a visit during the summer, so a commitment to any program isn't likely before that point.
