Since the start of the '01 season:
Teams off a bye: 17-14 SU, 16-15 ATS
However on 2 occasions teams off a bye played vs each other, so taking out those games, it's: 15-12 SU, 14-13 ATS
=============================================
Since the start of the '98 season:
(Corrected stats taking out off-a-bye vs off-a-bye games): 52-43 SU, 42-49-4 ATS.
That's surprising!
