Joe Mazzulla on building an identity and what he's learned about its challenges: "I think the part that doesn't get talked about enough is what the opponent in the league is doing... You want to obviously do your best to stay ahead of the trends... Where's the game headed? What are you trying to accomplish? How can you stay ahead of that? At the same time, you are relatively a product of what the defense and offense allow you to do at that particular moment. So you want to have your identities, but at the same time, you have to be flexible towards what your opponent is giving you, what they're allowing to happen, and where the league is headed."
