- Jeff Horner
Iowa product and D-League veteran Jeff Horner started the year in Belgium, which is only fitting because he's American. However, he was released by Aalstar after posting 0 points and 1 assist in 47 minutes, while still recovering from a twice-broken foot. He then took up coaching, starting at Des Moines area high school, moving to Grandview University, and has now joined Iowa University's player development program.
Horner was the first player acquired in the history of the Iowa Energy D-League franchise. This was for his local ties more than anything else.
