"Auburn is definitely number one right now," he says. "It is at the top right now. I am probably going to go on one more official visit, maybe two, but they have to live up to Auburn now. They are at the top of scale."
On Saturday, he watched Auburn put a physical whipping on Bama, its archrival, as the Tigers took a 28-18 victory.
"I was surprised by the defense," says Isom, who plays on both the offensive and defensive line for Lovejoy High. "They came out and had 11 or 12 sacks. I wasn't expecting that. That was crazy.
"The defensive end, (Stanley) McClover had what, almost five sacks. He is a monster out there. He is real fast. Those guys came out there to play. I like that. They got after it early."
Commenting on the overall visit, Isom says, "It went great. The game was everything I expected it to be, and then some. The people at Auburn were great. The fans were great. I like the campus. It is just a great place. I really like it at Auburn."
Going into his trip, coaches at other colleges had told him that the color and pageantry of a big game weekend on the Plains could sweep him off his feet. Isom notes the spectacle was an impressive as he hoped.
"They were right," he says. "It was just a great game. It doesn't get much better than that. It can't."
"I had heard a lot about it," he adds. "It lived up to my expectations and then some. I felt the electricity as soon as I got there on Friday. It was just great. It was overwhelming."
On Friday night, defensive end Alonzo Horton, who is redshirting this year, was his player host. On Saturday night, tailback/safety Tristan Davis was his host. "I had a great time with those guys," he says. "They are really cool. Just like people back home."
Commenting on what else impressed him, Isom says, "The campus atmosphere was crazy. Everybody was walking around with Auburn stuff on. I came up up there (Toomer's Corner) Sunday morning and it looked like it snowed there was so much toilet paper. It was great to be a part of that game and that atmosphere."
Isom made the official visit along with teammate Mario Fannin, who had previously committed to the Tigers. "It was cool," he says having his teammate with him. "He has been to Auburn a few more times than I have so he was showing me around. He was telling me some stuff he liked about it. He was with all of the other commitments like Neil Caudle, Zach (Clayton), Bart Eddins, Benjamin Tate. They were talking to him. It was great. I had met Bart and Neil before. I actually gave Neil my number."
