I think Prohm was a victim of his initial roster. He had a talented group of upperclassman- so he was all in the first 2 years to maintain Fred Hoiberg's program.
In years 4/5 he is trying to create a new culture is finding out that is hard to do. Also losing is a bad habit, hard to break!
The recipe for a great program isn't hard to identify- it's been the same as long as I can remember:
- Great on ball defense with shot blockers to protect the rim.
- Great rebounding (off&def)
- Players who can shoot. A lot of coaches and fans get memorized by great athletes. Great shooters is far more important.
- Make more free throw a than the opponent attempts. This means pressuring the paint.
The icing is strong 3 point shooting. The are top 20 teams that shoot poorly from 3, but they do the other things well. Do the core items and shoot well from 3 and you have a top 10 program.
