I would not call Wilson a running QB any more than I would Aaron Rodgers. They both extend plays laterally with their feet and are able to stress a defense because of it. Wentz, RG3, Etc, try to get up field with their legs more often..... And that is where injuries happen.
It is yet to be seen what camp Murray falls into, but if he tries to hit home runs with his feet, it could get ugly for him in a hurry. I don't care how elusive people think he is. It comes down to angles once you are beyond the LOS, and his chances are not good against LBs and DBs at the second level.
