Apparently 2012 signee Xavier Grindle was unhappy at Mississippi State on Friday so he contacted Pearl River Community College and signed with them that day. He has since decided to change his mind and come back to Starkville.
Grindle was a running back in high school but is expected to play cornerback at MSU. From the article, Dan Mullen is not too happy with the PRCC coach.
I don't know what happened in this situation, but based off stupid stuff I did when I was 18 I bet Xavier's coaches, and probably his parents, have given him a stern talking-to; and he'd like to go in the corner and cry.
