The passing and movement has improved significantly over the course of the season, but there are still times when guys are tired, shooting or flow is off, or they're backing off a bit to conserve energy. When the guys are moving and passing well, we get much better inside looks. So the point I'm making here is subtle, but essentially the 2 point success is not because we're looking to go inside like we did with Kofi, but because the flow of the offense is improving, and excellent when the guys are sharp.
I think the counter-argument is two-fold: you need the 3 point shooting to get the spacing and looks that get that high % of 2 point shooting, and that Underwood believes in the guys enough that they need to keep taking those 3 pointers and better averages will follow. "Build it and they will come."
FWIW, I tend to agree that we're more dangerous when we're getting good movement and attacking, but I don't fault the coaching staff for believing in our shooters.
