Of course he does because our "real problems" are a lack of talent on the offensive side of the ball. Most notably on the Oline and at the QB position. Aside from pass rusher, those were our most glaring needs last year and going into this this year and we did NOTHING to address them.
So, obviously when a runner talented enough to gain yardage when only 1 or 2 out of 5 linemen actually do their jobs in on the field, it makes a HUGE difference. He finds the holes or creates one, even with a sub-par line in front of him.
And when he is effective running, we don't have to throw, and when we do throw, teams are having to respect the run, so they can't double every WR and/or pressure our QB on every play.
Almost every team sport is about match ups. And having a talent like Gore on the field creates much better match ups across the board because teams have to focus on him and there is far less pressure on our mediocre WRs, Oline and QB. Without him to draw that focus away, well, we have all see the results.
Unless the Rams are in town, it's not a pretty picture.
