The #1 contributor to success is the student him/herserlf. The teachers and faculty, coaches, advisors, tutors, ancillary programs, facilities...it all contributes to the success of the student.
On balance, UNL has done very nicely - from 2000 to 2003, UNL had the most Academic All Americans in the entire NCAA. The only other DIV I school in the top 5 was Notre Dame. And Stanford, of all places, didn't make the top 10 (coming in at 13th - though that's probably due to lack of athletics than lack of academics

).
