I have them at -1.5 this early at 1.88 odds, I think despite that they lack personnel, they will have to bounce back in this game and the Villanova boys will have to find a way to win and get back the momentum in this series.
They struggled without OG, if he will not play, I think the Pacers will win. The confidence of the Pacers now is on the roof after they beat the Knicks by blowout last game, so I think they'll likely take the win. Currently the Knicks are -2.5, but this is already game 5, they might face the fatigue as they are undermanned and have not been using their bench effectively.
