I do fine his retirement timing a little interesting. He has had the present underclassmen starters, while losing many many top recruits to the portal, for three years. Overall on paper his top recruiting classes should have won a Championship, but they haven't. This program, as many would say, can "buy" any player at any time.....but it hasn't bought them RECENT Championships.
JCook during his tenure at Nebraska has won four Championships (2000-2006-2015-1017). However, the most successful program was Penn State under Russ Rose (7 total) and most recently Katie Schumacher-Cawley. I just read the latter has received her final necessary medical treatment and signed on Feb 14 an extension through 2030 for the Penn State's Head Coach position....Good for her!
My point is, no matter what decisions coaches, players and their parents make, only one team at the end of the season can say they are Champions.
