Its been repeated many times over the years that Hoiberg is an 'offensive genius' etc.
But as far as I can tell his offensive plan is pretty simple:
1. Space the floor to force the D to defend the whole floor.
2. Shoot efficient shots (3's, FT's, paint).
3. Be flexible, allow freedom, and exploit match ups.
Im sure I'm simplifying things, but shouldn't the assistants have a pretty good handle on this stuff by now? It obviously works and is a great strategy but doesn't seem that tricky.
Offensive theory is all well and good, but the trick is getting the players to execute properly, which Fred did. ISU was 31, 22, 17, and 15 nationally in offensive efficiency the last four years. He also gave players the confidence to shoot without looking over their shoulders. And, he was one of the best in the nation at post-timeout offensive efficiency, and led the nation one year. I remember the play he called in last year's Big 12 tourney with less than a second left in the half which led to Niang shooting a point-blank layup which, due to probably being surprised at being so wide open, he missed.
