ATHENS, Ga. - Isaiah Crowell, a top-ranked running back from Columbus, says he is signing with Georgia, giving coach Mark Richt the final piece of his "dream team" recruiting class.

Crowell, from Carver High, picked Georgia over Alabama in an announcement nationally televised today by ESPNU.

He is ranked as the nation's top-ranked running back by ESPN and Scout.com.

Crowell joins two Valdosta High players - tight end Jay Rome and receiver/defensive back Malcolm Mitchell - along with defensive end Ray Drew of Thomas County, one of the nation's top-rated defensive ends, as the cornerstones of Georgia's signing class.

Crowell made his announcement before sending Georgia his official letter. He would be Georgia's 25th signee.
