I may be in the minority here but I hope they get someone who has some experience coaching QBs...which would probably leave any former Cyclones out.
I think a good to great QB coach would make a world of difference in the offense, especially with ISU's young QBs...to me, it's probably the most important offensive coach. Someone who is dedicated solely to them and can stay on them about mechanics, help them read defenses and make pre-snap adjustments, and has the ability to get them to understand the decision-making it takes to play QB...someone who can get them to develop and improve all those skills...a real teacher...
It may sound obvious but I think it's tougher than it sounds...it takes a certain skill as a coach to relate those things and I'm not sure there's been someone like that the last few years because the QBs haven't seemed to develop like they should...although Rohach did come on at the end of the year, but against some bad defenses.
