I believe it was JIm Walden that coined the term "coaches graveyard" at Ames . However, I think ISU has a good history of ex-coaches who moved forward and became champions: Pop Warner (4 NC), Johnny Majors (1 NC), Pete Carroll (2 NC, 1 Super Bowl), Jimmy Johnson (2 NC, 2 Super Bowls), Mack Brown (1 NC), Gene Chizik (1 NC), and Earl Bruce (1 point loss in NC).
Now, with Matt Campbell, we are the coaches graveyard for opponents. (2018) Akron - Terry Bowden fired 9 weeks after losing to ISU, TTU - Kliff Kinsbury fired 4 weeks after losing to ISU, KU - David Beatty fired 1 day after losing to ISU, KSU - Bill Snyder forced to resign 1 week after losing to ISU, WVU - Dana Holgersen resigns and takes lesser job 2 months after losing to ISU. Next on the ISU early retirement list - Tom Herman. RIP.
