The Tigers hit just 3 of 23 shots (13 percent) before halftime to help Alabama build a 23-13 lead.
The starters made just one basket in 15 attempts.
Alabama jumped ahead 15-2 over the first 11 minutes, then the Tigers scored 10 straight. Releford scored six points to key an 8-1 run heading into the half before the Tide went into the big second half funk that left Grant bewildered.
"I can't explain the lack of effort, the lack of energy, the lack of execution," he said.
