To me the single strategy obviously works better faster, but I thing the ceiling is higher if you have multiple strategies. Also, using different approaches helps these guys prepare for the league. Every NBA team attacks ball screen differently depending on the team and players. I think Ks willingness to teach the whole game instead of just a system is one way he's grown the most as a coach in the last 10 years or so. It can bug us fans because we want to see the same system every year and identify with it. But I don't see any NBA teams running Dean's secondary break every trip down.
