The 6-foot-1, 306-pound Mack, who got his 21st offer from Ohio State on Wednesday afternoon, told AUTigers.com the trip "exceeded expectations," He spent time with head coach Gus Malzahn, associated head coach/defensive line coach Rodney Garner, and offensive line coach J.B. Grimes.
The time with Garner stood out, understandably, especially since Garner told Mack about past players of his such as NFL defensive linemen Geno Atkins and Charles Johnson. The 6-foot-1, 303-pound Atkins is a tackle and one of Mack's favorite players.
"We're about the same size. That's big for me because I know I'm a little undersized. I'm not the 6-4 guy that every coach wants to have," said Mack, who had 35 tackles for loss and eight forced fumbles as a junior. "Just to say that coach Garner has coached someone like him intrigues me. He would give me a chance because he wouldn't just say, 'Oh, this guy's too short.'"
Mack said he will visit Auburn again later in the spring and that he will "definitely be taking an official visit."
Nevertheless, Mack remains committed to Texas A&M, which got his pledge in October. Mack doesn't have any plans to visit College Station soon, but he's already been five times.
"Anytime I really wanna go down there, I just go," he said.
Mack did not say he had firm plans to visit Ohio State, but he did say the school with his most recent offer has a chance to get into the race for him.
"Ohio State could get in it, but I really can't say because I haven't been," Mack said. "But it's Ohio State. I would like to maybe give them a chance. I may visit there at some point."
Prying Mack from Texas A&M will be difficult. He's long maintained that he wants to play in the SEC and, as he said when he committed, the Aggies allow him to do so without leaving his home state. The campus is fewer than three hours from Gladewater.
Mack is No. 9 overall nationally in the 2015 Scout300 and No. 3 overall in the state of Texas.
