We know what his halfcourt philosophy is. We see players doing a bit of a circle offense coming from underneath from weak to ball side and catching the ball. They're supposed to shoot or drive there. And we know he likes to run pick and roll/pop at the top of the key with spacing from shooters.
The problem is this team doesn't have the decisiveness from DHam, the ability to finish at the rim from Gibbs/Purvis/DHam, the ability to be creative coming off the screen (Gibbs) or shoot (Adams). This allows opposing defenses to overplay Gibbs, or go under Adams and essentially neuter our offense.
It can be a beautiful system that empowers guards when it operates well (often in 2014), but it doesn't rely enough on the low block when you have a player like Miller there, and when the team can't run it, it looks like this mess we see today. When we play teams that don't have the athletes, suddenly there's an offensive system (like annihilating USF) . It's always there, but better teams can snuff it out. It's why we beat every bad team and struggle with every good team.
