Are you excluding these former ISU coaches whose career stature has far exceeded the Rutgers standard? Johnny Majors, Earle Bruce, Gene Chizik, Dan McCarney. Can we cite Rutgers head coaches who have moved on to significant careers and high regard among their peers?
McCarney had a record of 56-85 at ISU, with one 9 win season begin the high mark an nothing else better than 7-5. Not exactly Knute Rockne-like success. He was unceremoniously fired from his rebound gig at North Texas after losing 66-7 to an FCS team on homecoming. Ouch.
Chizik was a stellar 5-19 in Ames, bought himself a Heisman Trophy winner at Auburn, then was fired a whole 2 years after winning a natty by going 0-8 in the SEC.
The first two guys on your list I've never even heard of before (I'm only 40), but a quick check shows me that Bruce was unceremoniously dumped on his *** by a real football school after losing to Iowa in 1987. LOL
I would not say that those 3 guys went on to have anything even remotely resembling "significant" careers or high regard among their peers. I'll give you Majors.
