Your right I didn't really reasearch it like I should have but that is the the first story that comes up when you search about 4 year scholarships. The Big 10 is the conference who uses them the most and yes Iowa is doing it (71) for the past two years. ISU not so much.What makes you think only the big 10 is doing this? Or that it is conference policy? That was kind of my point why havent we heard what ISU is doing, if we arent offering multi years then Iowa has an instate advantage over us and if we are weird nobody has asked either way kind of odd it hasnt been covered.
Colleges, universities slow to offer multiyear athletic scholarships - Pittsburgh Post-Gazette
Of the BCS conferences, the Big Ten had the best track record for offering multiyear scholarships, led by Illinois, Purdue, Ohio State, Iowa and Michigan State, which offers four-year deals to football players as part of coach Mark Dantonio's policy. The Big 12, which was the only BCS conference to formally support the override vote, had offered the fewest, with Kansas State, Texas, Texas Tech, Iowa State, Oklahoma and Oklahoma State all having given two or fewer multiyear scholarships in two years.
