I don't have a big issue of Iowa keeping Brian as OC the rest of the year. I tend to go with the thought, you finish what you start. After all, there are 5 games left to salvage the season. It's not like Iowa can add a new QB or OL to its roster.
But we all know where this is headed. After the season, Iowa announces, "Offensive changes are needed and they plan to implement a wide open offense and shuffle the staff. Unfortunately, Greg Davis has retired, but they will find the best. Fortunately, Brian has agreed to stay on to support his alma mater as Iowa new/old OL coach."
