I know a lot of us our "superstitious" when it comes to not taking opponents likely. Over on the FB board, folks were worried about a let down against a horrid Albany team and yes while we nearly crapped away a 28 point lead, our overall talent was better than Albany, we were playing them at home, and because of that I think we would beat them 9 out of 10 times. Likewise our overall talent in hoops is better than JMU's talent, we are playing at home, and think that we would probably beat JMU 8 out of 10 times.
We should beat JMU by 8-12 points in my opinion, but as was postulated above there is a smaller chance the game is very close or that JMU outright wins the game. That would only happen though if JMU brought there A game and we played pretty poorly.
