Boston at Philadelphia

The old Zig Zag Theory will be in full force in Game 3. It's an NBA playoffs trend that simply says to bet on the team that lost the previous game, especially if it was a favorite. We saw it come through on Wednesday night, when the Pistons won and covered against the Hawks after losing Game 1 of their series. Plus, Philadelphia hit 19 of 39 from 3-point distance, and that kind of accuracy is unlikely to happen in consecutive games. We also can expect Boston to shoot better than 39 percent overall and 26 percent from beyond the arc, as it did on Tuesday. The past five meetings have gone UNDER, and the 76ers have stayed UNDER in eight of nine games while averaging just 104.9 points in their past eight. Boston is 12-5 UNDER its past 17 road games and 7-2 ATS its past nine games. Take the Celtics and the UNDER.
