This has been the problem at ISU for a very long time. They have always seemed to find some nice skill people, DBs and LBers, but the lines on both sides have been way below par. Now somehow CMC has solved the DL issues, which were the worst of the two, but the OL has just never gotten there. Hopefully they have the OL figured out with some better recruiting the last 2 years.
Takes years to build up that depth but only takes a couple seasons to unravel too. Iowa’s problem seems to be the opposite. Recruit and build up depth well everywhere but RB/WR.
