Iowa is now looking for a new OC, but Kirk Ferentz's son is the current OL coach and seems to be the leading contender. Davis was considered to be Iowa's Achilles heel.
I now live out here in Iowa. They said on the radio his last 4 bowl games coached they scored a combined total in 10 points in the first half of all those games. The general consensus is that the OC isn't the problem, the guy before him did horrible as well apparently, but it's Ferentz. He needs to go soon.
Got an extension along with a massive buyout after the 2015 season if I remember correctly. Think he was on the hot seat entering that year too.
