Don't have the 4.5 - would like it also - his underdog play is: UNLV +33.5.......he is hitting 6-2 on his college 4's and about 1-7 on his underdog, so take that for what its worth.....subscribed to powersweep for about 5 years now and can't remember him taking a dog this big - he is stretching to get a underdog win I think......
