Last year's Game 5 landed a 12.6 rating in the Miami-Oklahoma City Thunder series, likewise with Game 5 in 2011's Heat-Dallas Mavericks series.
Perhaps part of the reason why this year landed a low rating compared to the past few seasons is that in the past two seasons, Game 5 has fallen on a Thursday night, historically one of the best nights for ratings as far as the NBA goes.
Otherwise, you've got to chalk it up to the lingering (and totally insane) opinion that your casual basketball fan might have of the Spurs—that they're a dull team to watch.
While the ratings are nowhere near as low as the 2003 Spurs-New Jersey Nets NBA Finals (that Game 5 landed an embarrassingly low 7.7 rating), it is odd that they're still lower than 1999's Game 5 between the Spurs and New York Knicks that hit an 11.9.
The ratings for this series have been a bit disappointing, but that's only in comparison to the past four years, which have been record-setting for the NBA.
Ratings are still up compared to the mid-2000s, and the NBA is as popular as ever.
However, a stagnant league is not one that makes the commissioner happy, and only growth will satiate his hunger.
In order to spice things up a bit, perhaps a few changes could be made to the way it runs things.
