The win snaps the Lancers' season-long three-game losing streak as they improve to 16-6 overall, 10-5 PacWest, moving with a game-and-a-half of second place in the conference behind BYU-Hawaii. The Lancers host BYU-Hawaii Saturday.
Chaminade falls to 9-12, 7-7 with its sixth straight loss.
Deeb was 7-for-9 from beyond the arc and bettered his previous career-high of 15 points set last year at Cal State Stanislaus. His seven 3-pointers are the most from any player in a game in Head Coach Tim Collins's 10 years at the Lancer helm and just three shy of the program record.
"I haven't been shooting well all year so the last few days I've been working hard trying to get my stroke back and tonight it came back," said Deeb.
Ivan Patterson had 18 points and four steals, Justus Von Wright finished with 15 points, and Luke Evans chipped in with 11 points and a team-high six rebounds.
The Lancers shot 54.2 percent from the floor, including a 58.1 percent clip in the second half. They were 11-for-24 (.458) from downtown, the second straight game they hit double-digit 3-pointers.
But the difference in the game came from the reserves, which outscored the Chaminade bench 41-20.
"Those guys have been working hard and tonight they played really well, especially our guards," said Collins. "Our second group outplayed them in terms of intensity and effort. They were focused. That was a huge win, and those guys from the bench picked our entire team up."
In Saturday's 70-67 loss to Dixie State, the CBU bench combined for just 10 points, but nine of them came from Deeb and all of those in the final five minutes.
Tonight, Deeb had nine in the first 11 minutes and the Lancer bench had 21 of the Lancers' first 30 points and in the process they erased an 11-3 deficit with 11 straight points, five from Jalen Jury. Even Micah Sherman, who has two points all season, got into the act as his jumper gave the Lancers a 26-17 lead with 7:31 left in the half.
Sherman finished with a career-high seven points. Jury also finished with seven points, two assists, two steals and two rebounds.
In all, the Lancers outscored the Silverswords 37-13 over the final 14:48 of the first half. Patterson had eight of the Lancers' final 10 points of the half, capped by a buzzer-beating 3-pointer after getting a steal and driving the floor in time to give the Lancers a 40-24 halftime lead.
The closest Chaminade got from there was 14 points (62-48) with 8:51 to play, but Deeb answered with a pair of 3-pointers in a 12-0 blitz that pushed the Lancer lead to 26 with less than seven minutes left. The lead grew to as many 31 (83-52) with 2:39 to go.
"We found him a lot, especially when they were pressing us in the second half," said Collins. "We know that at any moment he can get it going, and he got it going tonight."
The 24-point margin of victory is the largest this year.
