Cody Zeller isn't there to anchor the post.
One of IU's major weaknesses is its lack of size and experience in the post. The past two seasons, Cody Zeller controlled the paint on both ends of the floor.
He was the main cog in Indiana's wheel. Zeller was Indiana's first option on offense. His presence and ability were usually too much for one defender. When double-teamed, he was able to find the open teammate.
Zeller's size helped set him apart from the competition. He was lanky but made up for it with height (7'0"). His possible replacements, sophomore Hanner Mosquera-Perea (6'8") and freshman Luke Fischer (6'9"), don't quite measure up. Seven-footer Peter Jurkin could be an option, but his experience is an issue.
He only played a total of seven minutes last season.
More important than size is talent and experience. Mosquera-Perea had a dismal freshman season (0.9 PPG, 1.5 RPG), and Fischer has yet to play a college basketball game.
Will Mosquera-Perea improve enough in the offseason? Is he really as good as recruiting services labeled him to be?
How will Fischer's game translate to the college level? Can he handle the pressure of replacing Zeller?
Obviously, Cody Zellers don't grow on trees, but the fact that IU's low-post situation is so up in the air and its prospects have so many questions surrounding them is a major concern for this season.
