Watching Russell scramble, I noticed he gets down or runs out of bounds. Dak injured his shoulder in a similar fashion against the Rams last season. You need to take the 5 and get down. I have to rewatch but that might of been a dirty play. The Rams linebacker drove Dak’s shoulder into the ground on purpose.
But that has nothing to do with Moore. Dak is going to do what he does when in the middle of his run. I for one wanted to use the threat of his legs more often. Even if he doesn't run, just that threat can pull the defense in and open up down field.
Injuries happen in sports. Gruesome, too.
Luckily I don't think it will be RG3 and Alex Smith devastating. RG3 was never the same after his injury in the 2012 playoff game. Heck, he was playing on one leg against us to end the season to go to the playoffs.
