College career
As a freshman at Providence College, Bentil started 23 of the Friars' 34 games, while averaging 6.4 points, 4.9 rebounds and 21.5 minutes per game. He began to come into his own toward the end of the season, as he posted five double-doubles during his last 12 games, including a 21-point, 10 rebound performance on March 4 against Seton Hall. Bentil broke out during his sophomore campaign, and he and teammate Kris Dunn – a consensus All-American – became one of the top one-two punches in college basketball. He led the Big East Conference with 21.1 points per game, 7.7 rebounds per game, field goal makes and free throw makes. He also finished fifth in the conference in field goal percentage, sixth in free throw percentage, fourth in rebounds per game and third in win shares. He started 32 of Providence's 35 games, scored in double-figures on 31 occasions, notched at least 20 points 21 times and tallied at least 30 points five times. Bentil recorded 31 points and a career-high-tying 13 rebounds on January 24 during an overtime win on the home court of eventual NCAA champion Villanova. Two and a half weeks later, he scored a career-best 42 points during a double-overtime loss at Marquette. The effort included a 14-for-17 clip from the free throw line and 12 rebounds. He hovered right around his season averages during the Friars' two-game NCAA tournament run, posting 20.0 PPG and 6.0 RPG. He played all 40 minutes of Providence's first-round effort against USC, recording 19 points and nine rebounds during the 70-69 win. The Friars then lost in the second round to eventual NCAA runner-up UNC, despite a 50-point combined effort from Bentil and Dunn.
