Duke backup quarterback moving to safety

Posted by ESPN.com's Heather Dinich

Duke coach David Cutcliffe had mentioned he might move backup quarterback Zack Asack, and he did -- to safety. Seems like the trendy thing to do in the ACC this year, as Florida State backup quarterback D'Vontrey Richardson also made the move.

This is good for Asack, as clearly he struggled leading the offense in the Virginia Tech game last year, and the staff wouldn't have done it if it weren't confident in Sean Renfree. It was hard not to wince during last year's game against Virginia Tech when Asack threw four interceptions and no touchdowns and completed 2 of 9 passes in the 14-3 loss. It was also hard not to wonder how much different the game would have been had starter Thaddeus Lewis not been injured.

Regardless, Asack can help the depth at safety where Duke lost Adrian Aye-Darko, who had 29 career starts. Duke also lost starting cornerback Glenn Williams, who had 23 career starts.

The staff is excited about Renfree's potential. He was rated the No. 43 quarterback in the class of 2008 by Scouts Inc. He decommitted from Georgia Tech in 2007.
