Honestly I was a major Newby critic last yr. He never showed much will, agility/elusiveness, and didn't seem to have the top end speed that made him a top recruit. Not sure if it was health or him improving in the off season but he looks much better this season IMO. Seems quicker, hits the hole, shows some wiggle at times, and also has fought for tough yards.
I like the trio of Ozigbo, Newby, and Wilbon combined with the threat of Tommy running on any given play. We get thunder (oz), lightning(34), Cory Ross like agility(Wilbon). Couple that with the x-factor, Tommy Armstrong running on any play and you have a lethal backfield regardless of who starts.
Sticking with the original posters question on Newby vs Ozigbo... I'd take Wilbon. He can make something out of nothing and I am still furious that the run game was so lousy early last year yet they refused to let Wilbon play at all!
