In addition, apparently when one of those recruits decides to go to a Michigan or Ohio St, they automatically go up to at least a 4* the very next day. See the Iowa RB recruit who switched to Michigan 1-2 yrs ago.
I willing to go half way on this whole “Iowa uses the 2 and 3 star players” narrative. However, I’d argue Iowa’s 3 best players are 4 star players. Wirfs, AJE, Stanley.
