Not sure that the Turnover Chain should have ever been more than a 1 year trick pony....That being said, if it makes the players more enthusiastic....Not really for me, as a fan, to say what works for the actual players.....
As for the dancing and jumping around on the sidelines....What's the alternative....If the players were moping on the sidelines....Would that somehow be better....?
And, it's disingenuous to compare this year's team's sideline demeanor to that of 80s, 90s and early 00s teams...Those older Canes teams were almost always challenging for national titles....Any slip up could end those national title hopes....So, yeah, they were much more intense than this year's team that was basically playing for not much....
