KenPom predicts a win by UNC tonight, 80-77, with a 63% likelihood.
The line, in contrast, is UNC (-7.5), and the money line is UNC (-370), or that you must wager 370 to win 100 with UNC.(*)
In short, KenPom sees the game as closer than the general public; it also interesting that KenPom has the game played on a "Neutral" court, when most observers give the Ford Field crowd as a home game for MSU.
