DePaul (6-4) led by as many as 12 points in the second half, but sputtered down the stretch in the second half with Garrett on the bench with four fouls. The Demons struggled due to turnovers and missed free throws.
It was a sloppy game on both sides, where DePaul turned the ball over 23 times and Chicago State (4-6) had 19 turnovers.
The Blue Demons shot 57.1% from the floor in the first half, but then shot only 26.9% in the second half.
When overtime arrived with the score tied at 62, it was McKinney 's energy off the bench that gave DePaul a key steal and layup to start the overtime period.
"When I got it, I took off, I wasn't stopping," said McKinney.
"That was big time for us," said Garrett. "That was the game changer."
McKinney contributed eight points off the bench, dished out four assists, and had four steals to go along with three blocked shots.
"Charles is important to us," said DePaul coach Oliver Purnell. "Arguably he is our best defensive player when he's engaged."
Equally important was the poise, leadership, and free throw shooting down the stretch by Garrett.
"Coach preaches six minute games to us a lot," said Garrett. "This time it was a five minute game. We made free throws and got stops to come out with the victory."
Billy added 17 points, five rebounds, and four steals on the afternoon.
Garrett's calm demeanor guided his team in the overtime period.
"I think it has something to do with my personality," said Garrett. "It's the kind of person I am."
Cleveland Melvin led all scorers with a double-double performance of 18 points and 11 rebounds.
Brandon Young added 14 points and five assists in the winning effort.
Chicago State brought energy on the road and had three players finish in double figures. Quinton Pippen and Nate Duhon led CSU with 18 points apiece. Clarke Rosenberg chipped in with 17 points for the Cougars.
The Blue Demons will next host the Houston Baptist Huskies on Wednesday night at Allstate Arena .
