Carroll averaged 17.5 points and 7.2 rebounds per game for the John Carroll Cavaliers in his junior season and, along with Alabama commitment Ron Steele, led the Cavaliers to a perfect 36-0 record and a state championship in 6A, Alabama's highest classification.
"I really like what Coach Kevin Stallings is doing at Vandy," Carroll told the Birmingham News. "I feel like it is the best place for me.
"It was a very difficult decision, but I know I will get the chance to get a great education at Vanderbilt and also play in the SEC."
Carroll transferred to John Carroll, a private school, from Minor High School after his sophomore season. He was selected to play in the Alabama North-South All-Star Game on July 16 in Montgomery, and scored 18 points and pulled down 9 rebounds in leading the North to a 98-85 victory.
"I think Vanderbilt is getting a steal," John Carroll head coach Marty Smith told the News. "DeMarre' has the ability to be a great 3-guard in the SEC. I think having the chance to play in the SEC and play for a coach like Coach Stallings is a big reason for his decision. His track record working with players at DeMarre's position speaks for itself."
Vanderbilt also recruited Carroll's teammate Ron Steele, but Steele committed during the summer to Alabama and Coach Mike Gottfried. Carroll becomes Vanderbilt's second men's basketball commitment for 2004; point guard Alex Gordon of Pensacola, Fla. was the first. Verbal commitments are not binding, but Carroll and Gordon have indicated they plan to sign with Vandy in the early signing period in November.
