A nice demonstration on Bucks defensive scheme. Starts with shutting the paint, giving up off the dribble mid rangers, always forcing the extra/cross court pass by heavy rotations and all that with personell well suited for that scheme (lots of IQ, length and athletisism).
Couple of thoughts raised by the video:
This demonstrated why IQ is so crucial defensively. Being a net positive defender is so very much more than defending well in iso situations. Its understanding rotations and being able to constantly read what your responsibility is if thing x happens instead of thing y ect. These are things that are hard to see during the game, for example backdoor cuts that didnt happen because of a smart help defense often can go unnoticed.
Being able to fight through/over screens is very important especially in this type of scheme. You can never die on the screen. You have to be able to atleast somewhat contest shots off the dribble and/or make the passing lane to the big smaller (and try your best to box out the screener if his defender has to contest the shot by ball handler).
I dont have any data to support this so I could be wrong but I think getting over the screens is an area where Fox could develope some especially if he wants to be an all nba level defender. He has all the tools possible (quickness and IQ) and he probably already is one of the best one on one pg defenders but I think he dies on the screens a bit too often considering his defensive potential. Again not any data to support that, just something that I noticed in his rookie year and from time to time after that.
