CPR had "ONE" winning season with Danny Mac and Chizik players going 7-6 with two of those wins being a squeaker one point win against Minnesota (this game included 4 Cyclone turnovers and being outgained by the Gophers) and the famous 8 turnover Nebraska game.His special teams were phenomenal in the early years. Heck, we were an onside kick legend.
The failing years had so many problems that I can't remember anything on the special teams. I wouldn't be surprised if they were essentially fine and just overshadowed, but I wouldn't be surprised by dumpster fire stuff, either.
I remember and appreciate the OSU and TCU wins during CPRs tenure but there was never any consistent success beyond 2009. The ceiling was 6 wins and a one-sided bowl loss to the likes of Rutgers and Tulsa (a team easily defeated during the same season). The ceiling was lowered to 3 wins after the 2012 season.
Here are two callbacks for everyone from those CPR special teams:
-2010: Having the holder throw for a two-point conversion into the wind against Nebraska, this game also included a missed FG.
