MORGANTOWN, W.Va. -- A couple of weeks after West Virginia added a piece to its quarterback puzzle, the Mountaineers have lost another one.Chavas Rawlins, a freshman who completed his high school requirements early and enrolled in January, has now decided to transfer after just one semester. His high school coach at Monessen (Pa.), Andy Pacak, said Rawlins is leaving school in large part because the quarterbacks coach who recruited him, Jake Spavital, is no longer at the school.Spavital left WVU to become the quarterbacks coach at Texas A&M.Coincidentally or not, Rawlins' decision also comes after former Florida State quarterback Clint Trickett decided to transfer to West Virginia. Trickett is expected to compete for the starting job next season with junior Paul Millard and redshirt freshman Ford Childress. Rawlins went through spring practice with the Mountaineers, but Millard and Childress took all the snaps in the team's spring game last month.Rawlins was the only quarterback West Virginia signed in last year's recruiting class. But already the Mountaineers have a commitment from a four-star quarterback for the 2014 class, William Crest of Baltimore.
