Before making any Pacers vs. Celtics picks, you NEED to see what legendary handicapper Bruce Marshall has to say.

Marshall, who for years was synonymous with the Gold Sheet, a famed sports betting newsletter, is an in-demand guest on numerous sports talk radio and TV shows across the country.

Marshall knows all five starters scored in double figures for the Celtics in Game 3. Forward Jayson Tatum led the way as he sank five 3-pointers en route to a game-high 36 points and grabbed 10 rebounds for his second double-double of the series and 10th of the postseason. Guard Jaylen Brown recorded 24 points and center Al Horford added 23 as he went 7-for-12 from beyond the arc.

The expert also is aware that Pacers guard Tyrese Haliburton, officially listed as questionable for Game 4, missed Game 3 and may be out for the rest of the series with a hamstring injury, but the team did not suffer offensively on Saturday. Andrew Nembhard scored a career-high 32 points and fell one assist shy of a double-double, while fellow guard T.J. McConnell recorded 23 points, nine boards and six assists off the bench. Center Myles Turner did notch his second double-double of the series with 22 points and 10 rebounds.
