Of the in-state misses this decade, I'm dead serious when I say the biggest miss might be punter Matt Haack. With Iowa's playing style, having an NFL-quality punter can be a big, big difference maker. Not offering him early or pursuing him very hard was a bizarre move, but the blow was softened by him not going to any of Iowa's rivals.
Going back to last decade, losing David Barrent and Dan Hoch in back-to-back years stung. And it would have been nice to have Adrian Arrington; back-to-back 6-6 seasons in '06 and '07 may not have happened with an extra weapon of his caliber. Finally, he wasn't the 4-star that some of the others were, but there's always a "What if" factor with Dorian Davis. He played as a true freshman and true sophomore on a pair of very, very good Tennessee teams before playing on the best Cincannti team ever in '09. What would Iowa have been like with him on the '08 and '09 teams? What if he had redshirted at Iowa and was a 5th year senior in '10?
