Well, plenty have won championships, few have won more than one. The fewest still two in a row. That pretty much sums it up. Again, the hardest thing for any team to do is repeat as champion.
Some here blame Muffet. Why didn't she see this coming? Why didn't she stop it? Doesn't she understand the nature of her players? Her team? People seem to forget history. Does anyone think Doug Pederson wasn't excited to win a championship with his back up quarterback, knowing his ace would return for the next season along with his entire team? Why didn't he stop what has happened? Why didn't he see 6-6 coming? For all the greatness of the Patriots even they struggled to win back to back, and that was 13 years ago. Was it Bill's fault they've failed to repeat since? Or threpeat then? Does anyone not think Muffet and her staff did everything they could to prepare this team to repeat? When the personnel remains the same, or even improves, repeating in sports is never about talent. It's always about the mental and psychological ramifications of success. Always. That my friend works on the individual, granular level. That is hard to pull back together and make work.
From my vantage when you reach a certain level the mental aspect of sports is far more the important thing. A well structured culture wins championships, but doesn't guarantee success. Year to year everything changes, and the human mind the most of all. This past game Arike, Mabrey and yes, Muffet, showed themselves victims of their own success. Championship teams face different hurdles than contenders and it has always been that way. Ask any member of any winning team why they failed to repeat and you'll get a million different reasons. If ND fails to win this year, and past is clearly prologue here, it won't be Muffet's failure, but rather the vicissitudes of human behavior when facing new challenges, new failures and new understandings in familiar,well worn environments. For this reason and this alone, Geno is the greatest coach in CBB history.
