"I guess he might have to just plough ahead get as much as he can in any gap he can find ?."

And that is what he's doing when he can find a gap. So when that happens people will say "see there's the Gurley of old"-when he's really not IMO. He simply is no where near the break away threat he was before. However, when the down is near the goal line he has amazing power to push D linemen back into the end zone-like his two tds against TB. And just maybe that will be his role from now on.
