Steve didn't HAVE to do anything. He FAILED to recruit complimentary players his entire tenure at Iowa State. The so called "roster imbalance" could have been rectified if Steve could have recruited the players to do it. It was like he had no relationships built with players or high school coaches before he came to Iowa State.
When you say recruit complimentary players IMO his inability to hit on the transfer market was the issue, not the high school kids. We were leaning on young underdeveloped layers for several years. Not every kid is ready to come in and contribute, there has to be some balance in the roster. IMO that is where the transfer market is incredibly valuable and Prohm wasn't able to capitalize there.
