The 2 quarterback system has worked at ISU before, Hardeman/Stanley and the one I remember best.....yes, I am old(er).....Amundson/Carlson. But with Amundson and Carlson, Amundson was a great tailback, so he played each and every down and was only the back-up quarterback. The next year after Carlson graduated, Amundson took over and was an All-American at quarterback. Then he went on to a couple of years in the NFL as a running back.
I think Arnaud is your quarterback for now. But, I also think you need to get Bates on the field in some capacity...some "special" plays that can make the defenses nervous when they see them both on the field. I am sure Chizik and staff have a few of those in mind. (You think Iowa won't notice and adjust this year if Bates lines up as a wide-out again?......lol)
What I saw was a confident leader in Arnaud for someone starting their first game. And what I saw in Bates was a very exciting player, a better runner, and maybe just a little bit of a "loose cannon" in his first action at quarterback.
It will be interesting to see how Chizik utilizes both players. Whatever the case, it's not a bad problem to have. You have a good quarterback, and what appears to be a more than competent back-up. A lot of teams don't have either, let alone both. Plus they are both only sophomores.
Sometimes competitions like this, if there is one, can be a really good thing I think. Kind of keeps both players performing at their best. At least we can hope for that, right?
