I would agree that our assistant coaches are as good a group as has been at ISU since McCarney's teams in the early 2000's. However, it is difficult to judge how good a staff is until you see where they end up 5-10 years down the line.
I think our issues today have less to do with how good our coaches are, but Rhoads took the wrong approach in building a solid program. IMO he did a poor job in building strong OL/DL in the first 2-3 years. I understand his desire to bring in speedy players, but games are won and lost in the trencches.
Even though Rhoads is from Iowa, I don't think he has a staff member that works the state of Iowa hard. It seems we go after the obvious guys, but we don't have an eye for the 2nd tier talent. The other mistake and Rhoads might have come to the party too late to save his job is the importance of recruiting JUCO players. Not only to fill gaps, but to fill positions where it is tougher to project developement of a 17 year old recruit to a 20 year old starting player.
