My memory is short so I’m going to keep this to the last 4 seasons, starting with your list. So far, comparing best NCAA tournament finishes for starters at old vs new school:
PSU-
Dean better
Hildebrandt worse
Nagao worse (still time to improve)
Truax worse
Iowa-
Lugo better
Desanto better
Eierman better
Woods better
Teske same
Franek worse
Caliendo better
Michigan-
Davison better
Gomez better
DeAugustino worse
Finesilver better
Griffith worse
Suriano same
Brucki worse
Storr same
Based on this data, you could make an argument that Iowa has done the best with improving transfers. I’m not sure I’d go that far, but I think it should at least dispel the narrative out there that Iowa’s transfers end up getting burned out or whatever. But really throughout almost the whole list most guys placement only changed by a couple places, hence my statement that most of the big name transfers “were pretty much the same guy they were before.”
IMO, the 2 biggest improvements were Davison and Gomez, who went from never making an NCAA semi, to making the finals.
