I think he can still run, but he needs to know when enough is enough and just slide, or run out of bounds. Russell Wilson is a master at that. The injury he got was freakish, it could have happened just standing in the pocket and getting his foot caught underneath while being tackled.
It should've always been based on model of how Russell Wilson picks and chooses his way of using mobility and scrambling- without having to take unnecessary hits and punishment.
Goodness knows Wilson takes more than enuff hits and pops in the pocket alone, with such a porous OL he's had to work with for years.
But when Wilson does have to either elude or improvise vs a rush, he either finishes it with a scramble run
out of bounds.. or he goes into a
slide before a defender can close in for a tackler.
What we saw with Dak in his big injury with Giants Logan Ryan, that was Dak trying to be a RB in physically shrugging off his stiff arm which only enrages a tackler
to bring even more force, more muscle and more determination to abstract more punishment on the resisting ball carrier.
Especially when it's a "designed" play call that
influences the ball carrier into that kind of head on mentality.
Now I do expect some continuing RPO designed plays with the QB running the ball in at the
goal line , when a great many of those ball fakes Dak is not even touched
because the play action handling is so well executed.
