The only thing Nebraska loses if they cannot play Martinez is the big play ability from two people in the backfield. With Martinez it leads to both he and Helu able to rip off that long run at anytime. Without Martinez it makes it very likely it will be Helu who rips one off with the small chance Green does as well.
It makes gameplanning easier but it will not change the fact that Nebraska pushed us around last year early and will likely do the same this year. They will get their yards but likely have less potential to get a score with a long run.
It'll be interesting. Sure, we likely won't get the gifts we got last year (although they weren't all gifts), but we also should be better off offensively. Nebraska's D isn't as good and we are healthier. Plus, I think we are better up front this year than we were last year. At least I hope so.
I think we can all agree, if Nebraska and Iowa State both play at the top of their games, Nebraska wins. If they both play an average game, Nebraska wins. Hopefully ISU can play just a little bit better game than Nebraska does.
