I am fine with Waters falling down on running plays if he means he doesn't fumble. Waters isn't ever going to be a great running QB. If we run him occasionally to keep the d honest, I am fine with that. But, his fumble percentage is unacceptable. The extra 1.5 yards isn't worth the risk of him fumbling.
Embrace the two-QB system, people. It is going to happen. That way, you can enjoy our 7 game win streak to end this season and our playoff-spot next season, rather than spending all of this time bitching about how much better we would be if your man-crush Sams got all the snaps.
