Custer, who appeared in 12 games for Iowa State, averaged 1.1 points per game while averaging 5.8 minutes per game in those contests. Custer was set to be stuck behind All-Big 12 Second Team point guard Monte Morris again next season.
“I truly enjoyed my time at Iowa State,” Custer said in a statement. “I was able to build relationships with people I’ll be close to the rest of my life and I will always cherish the moments I had here. Thank you to the Iowa State coaches, my teammates and Cyclone nation for the special opportunity.”
A 6-foot guard from Overland Park (KS), Custer was the second-ranked point guard out of Kansas. Custer hadn't played since Feb. 14 when he logged just one minute.
Custer was slowed upon his arrival by mono, and appeared in only five conference games, playing a total of 15 minutes.
When Morris was on the bench during the 2014-15 season, Iowa State relied mostly on guard Naz Long to run the point. The Cyclones now have three open scholarships for 2015-16 with Custer's departure.
“I appreciate the work and effort Clayton gave to our program this season,” coach Fred Hoiberg said in a release. “He has been a great teammate. I’ve enjoyed coaching Clayton and wish him the best in the future. I will do anything I can to assist him as he looks for a new school.”
