You are absolutely right, especially in the Zone as SU plays it (with M2m principles, as they say)
But logic says, the further out you are, the lower the percentage of made 3's is.
There is no defense against accurate shooting from way out. If you go that far out in M2M, they'll just go around you. You know that I am sure.
As you say, the weak spot in our extended Zone is the high post. And we do poorly against teams that have big men that can handles the ball and shoot accurately. Fortunately, there aren't very many college big men that can do that. And that of course requires the opponent to pull one of their big guys out from underneath, so if they miss ...
At the same time you have to look at the number of times we trap opponents in the corner and force turnovers.
