Halftime update: Miami 7, Virginia Tech 7

Posted by ESPN.com's Heather Dinich

MIAMI GARDENS, Fla. -- It's like a quarterback audition here in Dolphin Stadium. We've seen five total so far, if you count tight end Greg Boone.

The Hokies have officially reverted to their 2007 dual-quarterback system -- the same one they won the ACC title with but lost the Orange Bowl here with. Tailback Darren Evans is not having the same luck he did last week against Maryland, but is catching the ball well out of the backfield. One of the differences in this game has been Virginia Tech's ability to catch the ball, regardless of who is throwing it to them.

Miami had no reason to switch quarterbacks, as starter Robert Marve was moving the offense. The switch to Jacory Harris halted the Canes' offensive momentum, and they went backwards instead of downfield. Part of that might also be attributed to the fact that the Hurricanes are now down to their backups at both offensive tackle positions. Still, Miami needs to get back to what was working in the second half, and that was Marve. He came back in with 37 seconds remaining in the half.

Both teams need to be wary of each other's kick returners in the second half, because somebody seems on the brink of running one back.
