Experience doesn't make a quarterback immune to injury.
The 10 ACC teams returning starting QBs would be wise to keep that fact in mind. Even though the 10 QBs threw 91.5% of their teams' passes last season, a backup QB is always one hit or one awkward step away from playing.
Here's a look at the backup situation at each of the ACC schools.
In good shape:
Virginia returns Michael Rocco (96.5% of Virginia's passes in 2011), but he's in a battle for the starting job with Alabama transfer Phillip Sims, one of the top-rated high school QBs in 2009. Sophomore David Watford played in 10 games last season and is easily the best third-QB in the league.
Duke's Sean Renfree (88.0%) frequently comes out of games in the middle of drives to let his backups, Anthony Boone and Brandon Connette run special packages. While fans and media members are still trying to figure out the method to coach David Cutcliffe's offensive madness, Cutcliffe promises that things will get even trickier. He may have multiple QBs on the field at the same time for certain plays this year.
Experienced but untested:
Georgia Tech's Tevin Washington (89.8%) is looking to hand-off first, run second, and then pass in coach Paul Johnson's offense. Sophomore Synjyn Days has only thrown 12 passes, but he's also rushed it 48 times.
With the rebuilt offensive line in front of Wake Forest's Tanner Price (92.3%), the backup job is crucial. Brendan Cross has appeared in five games over two seasons. Sophomore Patrick Thompson got a handful of snaps in one game. Everyone else is a freshman.
Little or no experience:
