NBA on Christmas Day: 35 Years of Betting Data

by Al McMordie

Wednesday, Dec 25, 2024
Christmas Day is the NBA's signature television event (apart from the Playoffs), and features match-ups between the league's elite and/or popular teams.   This season, we will be treated to five games (all odds courtesy of BetAnySports):

San Antonio Spurs at New York Knicks (Knicks -8.5, 222.5)
Minnesota Timberwolves at Dallas Mavericks (Mavericks -5.5, 221.5)
Philadelphia 76ers at Boston Celtics (Celtics -8.5, 221)
Los Angeles Lakers at Golden State Warriors (Warriors -4.5, 221.5)
Denver Nuggets at Phoenix Suns (Nuggets -2.5, 232.5)

Let's take a look at the data for Christmas Day games, dating back to December 25, 1990.

Home teams:  61-53-1 ATS
Away teams:  53-61-1 ATS
Favorites:  60-53-1 ATS
Underdogs:  53-60-1 ATS
Double-digit Faves:  4-5 ATS
Double-digit Dogs:  5-4 ATS
Revenge-minded Teams:  20-24 ATS

Overs:  53-58-4 
Unders:  58-53-4

Teams off Win (vs. Foes off Loss):  22-30-1 ATS
Teams off Loss (vs. Foes off Win):  30-22-1 ATS
Teams off ATS Win (vs. Foes not off ATS Win):  29-36-1 ATS
Teams off ATS Loss (vs. Foes not off ATS Loss:  36-28-1 ATS

Teams off Upset Win (vs. Foes not off Upset Win):  8-10 ATS
Teams off Upset Loss (vs. Foes not off Upset Loss):  25-17-1 ATS
Teams off Back-to-Back Wins (vs. Foes not off Back-to-Back Wins):  23-29-1 ATS
Teams off Back to Back Losses (vs. Foes not off Back-to-Back Losses):  16-14 ATS

From this data, we can see that there might be an edge in playing teams off losses against foes off wins.  Since 1990, those teams have gone 30-22-1 ATS.  This year, there are four teams that fit the bill:  Spurs +8.5, Timberwolves +5.5, Celtics -8.5, and Suns +2.5).  Notably, home teams have done much better than road teams in this set of 53 games.  Home teams have gone 16-9 ATS, while road teams are just 14-13-1.  The home teams off a loss this season that are playing a road team off a win are:  Celtics -8.5 and Suns +2.5.  And if we break our 16-9 ATS set down further to Home Dogs and Home Favorites, we find they both have been profitable.  Home Dogs on Christmas Day off a loss have gone 6-4 ATS vs. foes off a win, while Home Favorites off a loss have gone 9-5 ATS vs. foes off a win (and Home PK'em teams have gone 1-0 ATS).

Consider taking the Celtics and Suns on this Christmas Day.

Good luck, as always...
