Against Minnesota, it was clear that Indiana's zone needs some work. The Gophers continually found holes in the Hoosiers' defense.
Luckily for IU, Minnesota missed a number of wide open threes (4-of-20), or else the game wouldn't have been close. Future opponents are going to watch the game film and realize Indiana is giving up open three-pointers. All they have to do is make that shot and the Hoosiers will be in trouble.
IU plays the zone in order to protect a defensive liability like Jordan Hulls. But is the zone worth playing?
Indiana's best defender, Victor Oladipo, isn't the same player in a zone. He does best in a man-to-man scheme where he can disrupt the opponent's best player. Taking him out of his element only hurts IU's defense.
The zone allowed Minnesota to dominate the glass. IU was out rebounded 38-25 (17 offensive rebounds). When playing man-to-man defense, you know exactly who to box out.
It's the player you are guarding.
In a zone, there isn't a direct defensive assignment, so opposing players slip through the cracks, leading to offensive rebounds.
If the Hoosiers are going to continue to play zone, they must show that they can use it to force turnovers while still rebounding effectively.
