I'm going to throw in a new theory here. Some of the top teams, like GSW and Houston, are build on superb 3pt shooting. It's simple mathematics that if your FG% for 2pointers is 50, shooting anything over 33% from 3pt range will improve your result. The problem here is simple, when ever you have a shooting slump, you lose.
Mike Malone obviously decided to go the other way. For him 3pt shooting seems to be secondary as long as the wing players defend and rebound beyond the average (and that should not change from one game to the other). That's the way to grind a W and when the 3pt shots land, you win big time.
I think there are two indicators for that theory. Ben Mac keeps playing as a starter and he doesn't make too many 3pt attempts. If they don't fall, it doesn't matter as long as he keeps his man in control. I have no doubt about it, Ben Mac will become a really good 3pt shooter, but to be on the court he has to first be a good defender. That is the qualification that makes you a rotation player. The second indication is Casspi, who was considered to be the tall 3 pt shooting SF. He basically doesn't even consider them now. He's been ordered to drive and score or draw a foul. After being a terrible FT shooter for 5 seasons, he is now deadly from the line. Again, as long as Casspi defends and grabs the rebounds, he's OK. His assists are all bonus and DMC and Landry will profit from that. They just need to be alert, because they come with speed.
So Malone goes against the stream. For him 3pt shooting is a bonus. You're not going to be a shooter in his system if you're not a good defender.
