Kriener was pretty darn solid all of last year. Nunge has some big shoes to fill, but he also needs to prove he can stay healthy.
Jordan will be good offensively for Iowa, but Iowa takes a step back on the defensive end whenever he's out there. I see Iowa playing that zone as their primary style of defense the entire year.
I think a big thing for Iowa will be their bench. Their starting 5 will be J-Bo, CJ, JW, Connor, and Garza (most likely), so you then have Nunge, Touissant, and Patrick to round it all off. Fran will also likely play the freshman in some capacity.
