When you camp out 2 post players in the paint on offense every possession you are going to neuter the guards and kill spacing. Back to the basket post play is inefficient.
Using the bigs on the perimeter to set screens and catch on the move would have helped the offense tremendously. We saw a taste of that against gonzaga. If you play an uptempo offense and send Mika immediately to the post with his back to the basket in transition then you have a flawed scheme. You need your big to either stop on the perimeter for a pick, run to the rim or run to the corner if he can shoot 3s--the worst thing a big can do in transition is put his back to the basket and clog the paint/slow the pace.
I think our guards struggled so much this year that they NEEDED bigs to play on the perimeter to screen their defender and prevent teams from clogging the paint on us.
