No, Iowa vs. Nebraska will be the biggest game in the state of Iowa in 3 to 5 years. I stand behind that and have said that since this talk of NU in the Big 10 started. That doesn't mean that Iowa vs. Iowa State should go away.
Iowa has played 2 rivalries in the Big 10, one of which is very competitive, and neither has taken away from Iowa-Iowa State. I've said it before, Iowa-Nebraska won't take away from Iowa-Iowa State, it will take away from Iowa-Minnesota, or Iowa-Wisconsin.
It sounds like Nebraska is looking at Wisconsin and Penn State as rivals, NOT Iowa.
Matt, you'd catch a lot less hell around here if you would just admit you don't like ISU, hate Jamie Pollard with a passion, and think we're a second rate school. It's like Hawkeye fans who won't admit they're bandwagon jumpers and would have been ISU fans if we had beaten Iowa for 15 straight years. You can deny it all you want, but it just irritates people. Just admit it. It's a lot easier to put up with hatred when the person is forthcoming about it.
