Here’s what we know for sure regarding the Virginia quarterback situation heading into Saturday’s season opener against Division 1-AA William & Mary:  

1) Sophomore Michael Rocco will start. 

2) At some point in the game – perhaps several points – true freshman David Watford will be inserted and asked to execute a “limited menu” of plays. 

What we don’t know is how Rocco will perform or whether he might suffer an injury that would cause him to leave the game unexpectedly. Should Rocco’s performance or health necessitate an unforeseen removal, Coach Mike London said Wednesday that redshirt sophomore Ross Metheny would be next in line under center. And not just for the season opener, but for the foreseeable future.

“If Michael (Rocco) is getting the job done and with some of the limited things we’re planning on doing with David Watford, if Michael’s getting the job done, then we’ll stay that way,” London said during his segment on the ACC coaches’ teleconference. “If not, if his performance is not at a level that’s high enough to help us achieve what our goals are, then Ross (Metheny), who’s been in the offense himself, will have an opportunity.”

Rocco played sparingly in six games last season behind fifth-year senior Marc Verica. Metheny logged playing time in five games in 2010. Watford enrolled at Virginia in January. 

Metheny and Watford were listed as interchangeable at the No. 2 quarterback spot on the depth chart Virginia released Monday.
