RG3's gotta learn to slide--that injury doesn't happen if his leg doesn't go flying up just as the DT-92 Devastator came roaring in on a low-level run.
Sliding didn't help Trent Green. Staying in the pocket didn't help Joe Theisman. Its a rough sport. When you have 300lbs guys running full speed into 200lbs guys something is going to give. Usually the 200lbs guys bones.
