Ball State was the right side in this game, it was just more right early in the week when they were -6. Once the line got to -7 it became something close to a coin toss, which is about what you'd expect out of a game that ended with a push for late bettors.
I jumped on CMU when it opened at +7 and BOUGHT the 1/2 point! +7.5 = $$$! RIGHT SIDE for me!
