How Rest Day Stats can Give you the Edge in Your NBA Predictions

We know you have been using our NBA rest days stats to make better decisions. Let’s take a deeper look into it!

Is there any statistical edge to get over the sportsbooks? When NBA betting, closing NBA number by a point can be beaten and it is possible to add an extra 4% to the winning percentage. Taking an extra half-point on 2 or 7 makes it much more valuable than taking an extra half-point on 8 or 3.

The chart tracks how the league average differs for three different possession based stats: Offensive efficiency, defensive efficiency and pace (the number of possessions per 48 minutes).

And these applies the numbers to seven different conditions; 4th game in 5 nights, 3rd game in 4 nights (played yesterday), 2nd game of a back to back, 3rd game in 4 days (rested yesterday), 1 day rest, 2 days rest and 3 or more days rest.

Offensive Efficiency

-1 Points/Per 100 Possessions – 4th game in 5 nights
-1 Points/Per 100 Possessions – 3rd game in 4 nights (played yesterday)
-0.1 Points/Per 100 Possessions – 2nd game of a back to back
-0.2 Points/Per 100 Possessions – 3rd game in 4 days (rested yesterday)
-0.2 Points/Per 100 Possessions – 1 day rest
+0.3 Points/Per 100 Possessions – 2 days rest
-0.3 Points/Per 100 Possessions – 3 or more days rest

Defensive Efficiency

+1 Points /Per 100 Possessions – 4th game in 5 nights
+1 Points/Per 100 Possessions – 3rd game in 4 nights (played yesterday)
+0.9 Points/Per 100 Possessions – 2nd game of a back to back
– 0.4 Points/Per 100 Possessions – 3rd game in 4 days (rested yesterday)
-0.4 Points/Per 100 Possessions – 1 day rest
-1.1 Points /Per 100 Possessions – 2 days rest
-0.5 Points /Per 100 Possessions – 3 or more days rest

Pace
-0.8 Possessions – 4th game in 5 nights
-0.3 Possessions – 3rd game in 4 nights (played yesterday)
-0.2 Possessions – 2nd game of a back to back
-0.2 Possessions – 3rd game in 4 days (rested yesterday)
-0.1 Possessions – 1 days rest
+0.5 Possessions – 2 days rest
+0.5 Possessions – 3 or more days rest

The numbers for a team playing their 4th game in 5 nights and 3rd game in 4 nights is what we would expect, the offense goes down by a point and the teams give up a point on average throughout the NBA. Remember that the books will know this but they might try to over-adjust the NBA betting lines, if the game line is more than 2 points off what it should be then the bookie is over-inflating the line due to the public’s perception of the effect of rest on the team.

The number that stands out for me is teams that are coming into the game with 2 days rest, the NBA average shows teams in this situation are playing at their optimal level. The teams only score 0.3 points more than the league average but the defense tightens up by 1.1 points a game. Another point I found interesting but it makes sense is that teams scoring go down on 3 or more days rest, the shooters are like the rest of us, a little slow getting back to work after a long weekend.

Of course, those numbers represent the NBA as a whole; the chart can extrapolate which teams are the best under each circumstance. For example two of the worst teams this season have played under some of the worst conditions, the Indiana Pacers and the
