It is a blow, as Evans was a PROVEN RB, but they have much more TALENT behind him IMO, so the drop off may not be all that much... especially as the season moves along. Still, Evans was proven and had a great season... everything else is just questionable potential.
I think for playing against our defense, Ryan Williams is actually a bigger threat. Evans would try and go through us, and he would get eatin' alive. I suspect we see a lot of dumps and screens to Williams and the guy is MAJOR threat with some space. He's elusive and has great speed. We're gonna have to keep an eye on him. The other guy with some experience (though very little) is Oglesby. Kind of an anomaly in that he's got good speed but he's more known for his power. He's a bull and will try and his damnedest to run through our line. Then there's David Wilson who I'm sure they would have liked to redshirt. More talent and no experience. It's worth noting that Williams was the #3 RB in the country and Wilson was #4. The talent is there. Hopefully it'll take them a couple games to get acclimated. Not to mention, they shouldn't be getting much help from their o-line in this game. They are going to try and short pass us to death... and our staff will be prepared for it.
