Unlike recent games, DePaul (5-2) got off to a better start in the first half and led by nine at the half.
“I think it has everything to do structurally with how you defend and rebound,” said DePaul coach Dave Leitao. “You get more opportunities when you stop the other team from scoring. We weren’t as sharp as we could be, but we were sharper than we have been.”
The Demons did get it done on the glass and with defense. DePaul outrebounded Lamar 45 to 30 and held the Cardinals to 30 percent from the field in the contest.
The Blue Demons held Lamar’s leading scorer and rebounder Colton Weisbrod to just six points and nine rebounds.
DePaul also dominated in the paint where they outscored Lamar by a 44 to 18 margin.
After scoring just nine points in a loss at Northwestern on Saturday, sophomore guard Eli Cain was back in form and led the Blue Demons with 21 points and seven rebounds.
“My teammates found me here and there and I had a lot of free throws,” said Cain.
Billy Garrett, Jr. added 15 points and senior guard R.J. Curington came off the bench to contribute 11 points and six rebounds.
Tre McCallum collected 10 rebounds and chipped in with eight points.
Lamar (4-4) was led by 21 points from Dorian Chapman and 10 for Zjori Bosha, both of whom came in off the bench.
