When a math total has a large enough difference to the posted total, we use the oddsmakers knowledge against them. Because we store each over and under differently in each sport, the over and under angles will have different records, but in reality one could combine them for an overall record. The under version has gone under 727-423-34. Oh, and yes it even applies after one game. Though admittedly it gets even more fantastic starting week 5, this angle and many in every sport often sees early season overreaction.
