Christmas Day Unders

It's no secret (at least it shouldn't be) that unders are extremely profitable on Christmas. Since 2005, Christmas Day unders have +14.6% ROI.

Of course, you shouldn't blindly bet unders, and for good reason. Early games have been significantly more profitable to the under than later ones.

Full Game Unders by Tip-Off Time — Since 2005
Noon ET to 4 p.m. ET: 21-11 (65.6%, +$902, ROI 28.2%)
5 p.m. ET to 10:30 p.m. ET: 23-20-1 (53.5%, +204, ROI 4.6%)

The total in Sunday's Suns vs. Nuggets game is set at 230.5 as of Christmas Eve. If it closes at or above that number, it would be the second-highest over/under on Christmas Day in more than 45 years.

Highest Over/Under on Christmas — Since NBA-ABA Merger (1976)
233.5 — LAL/GSW (2018; 127-101)
230.5 — GSW/MIL (2020; 138-99)
229.5 — BKN/BOS (2020; 123-95)
229.5 — HOU/GSW (2019; 116-104)

Tired: Unders on Christmas. Wired: 2H Unders on Christmas.

Christmas Day second half unders are 49-25-2 (66.2%) since 2005-06. When fewer than 100 points combined are scored in the first half, the second half under is 21-6 (78%) in that span.

Looking for more of an edge? Games listed at 3 p.m. ET or later on Christmas are 34-13-2 to the second half under since 2005, too.

Here's one more stocking stuffer: First half overs are 12-3 in the past three seasons on Christmas Day.
