It's very clear to me. The whiners ran wild against the Rams and won all those games. In the NFCCG, they gained 50 yards on the ground which forced the game into Jimmy Gag's hands.
If the whiners run the ball well, we're toast. If we stop them and force them to go via the pass, we got a good chance.
It also helps with Stafford being healthy and the offense able to move the chains and get points.
