Jerry Jones says the Cowboys will look to add a veteran quarterback to serve as Tony Romo's backup in 2012. That likely means third-year man Stephen McGee will be third on the depth chart once again. "That's one of the things we'll see how it evolves," Jones said. "We like the progress of McGee. If somebody really has to start taking snaps, you'd like to see a guy with more experience. Now Houston did go pretty far with a third-team quarterback without a lot of experience. I do know it can happen. An inexperienced one can get you pretty far down the road." McGee, who Dallas drafted in the fourth round in 2009, has started only one of the three NFL games he's played.
