I know a fair amount about several of the players going to these schools as I am from the Des Moines area.
UNI-is loaded with Des Moines area kids as usual....they picked up a RB Zach Cutkomp who may well play DB at UNI and another DB from Ames that is a burner in Sam Tim
SDSU-Walker Woods was a solid high school back at Waukee, although probably the fourth or fifth best back in his league behind Cutkomp among others
SIU-I saw they signed a lineman from the area named Ryan Wood
