I voted for Gore because he doesn't get the credit I think he deserves. In all of my 29 years on this planet, he is by far the BEST 49er runner that I've seen. Too bad all he's ever played in on the pro level are in rickety one dimensional systems. I like V. Davis too, but he doesn't intrigue me more than #21. Gore plays like a much larger brute and I'm pretty sure defenders feel the same way.
Willis is awesome but he needs to learn how to beat/shed or flat out avoid being isolated on screens. He got knocked around pretty ugly this year on those and I think I remember one play in particular late in the season he pretty much got flipped and it hurt to watch.
