Covid and the door to the transfer portal being thrown wide open have really done a number on high school player recruitment at the power 5 level. But these things are cyclical. The Covid super seniors are all gone, and the portal will be full of players who put their name in but can't find a home. There will always be a need to recruit and develop young talent at a place like ISU.The "solution" is to find and keep your core players. High school recruiting is used to try to find the next Lipsey, Momcilovic's. You take flyers on a few more high school kids, hoping they can quickly develop into a "core" player. You then supplement these core players with high quality transfers.
Most high school players won't be a "core" player. That's fine. When it is apparent they may be better suited in a different program, let them leave to pursue the playing time they need.
