Grant was awarded a scholarship before last season.
It remains to be seen how the touches will be divvied up among the three tailbacks this season, but the backfield's not as crowded as the one he joined in Tuscaloosa out of Opelika High School.
"It was a tough decision," Grant said. "I loved coach Malzahn and his offense. After talking to coach (Nick) Saban and how they wanted to utilize me and trying to get away from home. Every student at my high school was like, I want to get away from home. So I did that. Then I realized that it really wasn't for me. Coming back here, I feel like I made the right choice."
