Mazzulla absolutely has his flaws, and some of the blame last season is on him. But I'll also acknowledge he was put into a pretty rough situation finding out right before the season that he had to lead this club, and also some of their assistants from previous years were poached away too.
At least this offseason, Wyc + Brad have surrounded Mazzulla with great help and assistance on the coaching staff, and I think having JVG around is huge too even as a consultant. And if Mazz doesn't work out, guys like Cassell or maybe even JVG could be next in line as a "Plan B". But I hope it works out with Mazzulla, I don't think he's "evil" nor is he "unlikable". He already seems way more comfortable speaking with the media and is very honest + having fun from time to time. I imagine last year he felt enormous pressure and so he was a lot more stoic and serious.
