Dangeruss and Miller. Everyone knows Beastmode is our workhorse, and our D will be more hyped for this than anyone.
Niners will be expecting runs all day, but Wilson has to be able to be on point to control tempo and extend drives. Of course having Harvin in there makes him the best wildcard we have, and in theory, every receiver becomes that much more dangerous. Miller has some damn good hands on him, and I'm sure the Niners will be least worried about him. If we can use Miller more, it will pay off big time.
Edit: I guess Miller is my darkhorse, and Wilson is my early impact player.
