They are also playing aggressive switch defense on the pick and roll. They need to run a nice tight little middle pick and roll between Fox and a shooter. Get Fox into the middle of the paint to either finish or dish back out. Also, run some of that through Bogdan as well. He's big enough to be able to keep bigs on his side and has the length to get the ball up to the backboard with full ball control.
And that's where either having the right coach for your players or the right players for your coach comes in. Walton needs certain types to be able to run his defensive sets. Switch ability, length to help, and quickness to run back out are all important.
