Tar Heels QB depth a concern Posted Aug 23, 2005 It's a good thing that senior quarterback Matt Baker was up to speed in a weekend scrimmage because the Tar Heels don't seem to be getting any deeper at the position. Sophomore Roger Heinz missed most of last week's practices and is considered out indefinitely with a back injury. Freshman Cam Sexton has been rehabilitating a broken ankle and his status for the season remains uncertain. (Kinston Free Press)
