The 6-3, 260-pound lineman signed with Auburn on Wednesday after announcing at a ceremony at his high school Tuesday night. However, he had second thoughts again on Wednesday morning and almost switched to South Carolina, where he was heavily leaning last week..
Capable of playing both sides of the ball, Isom is expected to get his first chance on defense as an interior lineman.
"It wasn't an easy decision," he told Inside the Auburn Tigers. "I was still thinking about it when I walked up to the podium before I decided that I wanted to attend Auburn.
"It's a big step in my life," he added."I had to make a decision from the standpoint of being a student. The academics there at Auburn just got me."
Isom noted that he plans on majoring in sports medicine or a related field. His parents both noted that they approved of the decision, both citing their respect for Auburn's academic program.
Byron Isom is shown with his parents on Tuesday night at Lovejoy High.
"At the podium--I made my decision up there--and I was thinking about it the whole time. That is what I felt was right in my heart."
Auburn is expected to sign his teammate and friend, Mario Fannin, on Wednesday.
Isom came very close to publically announcing for South Carolina last week, but couldn't pull the trigger then, notes Lovejoy High coach Al Hughes. "This kid has really wrestled with his decision," the coach says.
"I was still thinking about it on Tuesday and I told everybody I didn't know where I was going when they were asking me and I really didn't know," said Isom, who had all but made the decision to be a South Carolina Gamecock a week earlier. "Auburn is just where I felt good at. It is close to home and everything."
Fannin and Isom are two of at least 11 players on the Lovejoy High team expected to sign scholarships on Wednesday.
Isom, who can play both offense or defense, said, "Auburn said I will get down there and play defense until I want to play offense. That is a winning program and I will do whatever I can do."
