A member of the Scout 300 and ranked as a safety, the senior becomes the fifth projected defensive back on the UA's 2015 commitment list. He was visited multiple times by Alabama assistants in the spring before camping and earning a scholarship offer in June.
"Just the relationship I had with the Alabama coaching staff when I went to camp," Harrison said of his pledge. "On my last visit, when I visited with my mom and brother, they made it feel like home and made me feel comfortable and I got more comfortable with the coaching staff.
"It feels great to know that one of the best football programs in the nation wants you that bad to come play for them."
Harrison also favored the academic atmosphere in Tuscaloosa.
"The academic part, they have the major that I want (sports medicine) and there it's just a family vibe there and they have great players and great coaches," he said.
As Scout projects, defense will be the high school quarterback's home once he begins his carer in Tuscaloosa after graduating in December.
"They are going to utilize me at safety," he said. "They are losing three safeties this year. Early playing time definitely made an impact to go there. Yeah, I will be playing early."
Alabama retains its No. 1 team recruiting ranking, with 20 current commitments, on Scout following Tuesday's news. Harrison is the No. 293 player in the country, as well as the No. 16 safety.
