QB (2)- Prescott and Cooper Rush. Unless Rush plays really bad next week or the last preseason game (in which he's likely to get most, if not all of the snaps) there's almost no way he clears waivers to slide onto practice squad. We're set for a decade it appears with Prescott but Rush seems to have quality developmental traits and with another strong preseason next yr, could becomes the legit #2 or a very valuable trade piece. If they don't think Romo would return should Prescott go down, then maybe they add a new veteran backup after final cutdowns and keep 3 QB's. But for my roster, I assume Romo is Plan B.
