Henry, a 6-foot-6, 230-pound forward, averaged 3.2 points and 10.6 minutes in 35 games during his sophomore season at Illinois last year. He will sit out next season and have two years of eligibility remaining per NCAA rules.
"I really like what they have to offer me," Henry wrote in a text. "I like the style of play that the coaches run. I like it because it's a new start for me, and I think I can really help them get this thing off the ground."
Henry attended Orr High School in Chicago and was ranked No. 97 in the country in the Class of 2011 by ESPN. He played club basketball for the Mac Irvin Fire, which is also the program that current DePaul forward Jamee Crockett and Blue Demons recruits Billy Garrett Jr. and Thomas Hamilton Jr. played for in high school.
"I think he will be in a good situation at DePaul," Mac Irvin Fire coach Mike Irvin said of Henry. "He will play a lot of minutes when he is eligible. Excellent pickup by [DePaul assistant coach] Billy Garrett."
Henry joins Garrett Jr., who is ranked No. 94 in ESPN's Class of 2013, Hamilton Jr., South Plains College (Texas) sophomore center Forrest Robinson, Citrus Junior College (Calif.) sophomore power forward Greg Sequele and Oak Hill Academy (Va.) senior guard R.J. Curington in DePaul's recruiting class.
