It's crazy how much doubling him worked for Purdue. When Garza got doubled, the rest of the Hawks did not cut to the paint, or space properly around the arc. Doesn't help that Garza never hot-potatoes the ball to beat the double team, he needs to be faster at passing.
It seems the key to beating the Hawks is double Garza every time he touches it in the post, because he won't pass it quickly enough, and the rest of the Hawks won't properly space the floor.
