Lots of both. And there isnt a guy who plays RB and OL, so we'll go with what we can get.
The OL could be improved, sure. But Moss has 40 yards of open green in front of him at one point yesterday, he took forever to get his feet moving (almost like a cartoon where they are running in place trying to get going), and then when he finally did start running he tripped over his own feet for a gain of 6 instead of 60.
We could improve at RB and see an improvement in our run game.
