you can come up with all the data in the world, I don't think it is relevant in this case because you are asking a team to do something they haven't done all day. It would be different if there was some life on offense, but aside from the uptempo series at the end of the half which Iowa couldn't go back to because it was effective, this was the only sign of life. Now, I guess you could say that maybe the coach thought they had figured things out finally and would be able to move the ball again, but I highly doubt that.
I said before, it is so crazy to me that Ferentz's coaching philosophy is designed to keep games close, regardless of the level of opponent, so that games typically come down to a few plays. And yet he seems scared to death to take a chance when those plays are presented to him.
