Well the ISU staff offered Render and wanted him to play at their school so it could have just been as easy for him to play instead of Good Jones. It is just logical.
Reynolds was a late offer in the 2014 class
In 2015 when Meeker and GJ were being recruited ISU offered all of the same prospects as Iowa. Iowa got who they wanted and Meeker and GJ chose ISU instead..... Iowa got 5 OL that year from Iowa so taking 7 would have been stupid.
Do your homework
Also I could be wrong but IIRC I don't think anyone wanted the Paulsen twins but Iowa. Obvious to see why now
