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 goes under at a rate of 1056-707-34. When the teams combined for at least four interceptions last game, it goes under 218-137-8. When both apply, it has gone under 20-6 since 2011.
