A perfect day in the high 60s, mid 70's?
Weather isn't going to be a factor whether it rains or not.
1. Our field is one of the best in the nation and it won't turn into a swamp like the crappy old field at Kinnick.
2. We have an experienced RB in A-Rob. He has been very solid hanging on to the football and Arnaud is also good at protecting the ball when he is running with it.
3. Iowa is a run first offense. Rainy conditions would force them to run the ball more then they normally do which would allow ISU to really load up the box on them. With no SG to worry about it isn't a scary proposition there at all.
4. Our WR's... They handled the rain in Iowa City last year very well. I don't think it would affect them at all.
With those points made I think you can see that rain or shine ISU will have the same plan of attack. The weather isn't going to change it much if at all.
