Princeton's offense is able to keep up with Cornell's because of its efficiency. The Tigers shot 49.0% in the first game and 37% from deep. They won that game 75-68 on the road despite turning the ball over seven more times than the Big Red did.
Cornell has a weak defense (allowing 48.5%/ #353 two pt D). Princeton offense #3 in Ivy and gets to the FT line a lot and should win again here at home as they already beat Cornell on the road.
