Are We Really Shooting Worse?

Lots of people are saying this is one of the worst-shooting teams of recent memory. I know it seems that way, especially last weekend – but let’s look at some data and not trust our lying eyes.

So, using the great site Sports Reference, I pulled down game stats for the past five seasons. I then did some analysis.

First, I ran out FG% by game for the past five years, and did some graphs to see if I could see trends. The game-by-game graphs were too volatile, so I added four-game rolling trendlines. That seemed to show that this team was under earlier teams – but then I realized that our FG% was only part of the equation.

If you are a bad-shooting team, but your opponents shoot WORSE, isn’t that the stat that really matters?

So, I went back and added a rolling cumulative percentage, game by game, for both us and our opponents. THEN, I did a column showing the cumulative game-by-game difference.

Here are the results, both through 18 games and through the end of the year, showing both our FG% and the difference with our opponents:

2010-2011 — 47.7% through 18 (up 8.7%), finish 45.3% (up 5.9%)

2011-2012 — 43.2% through 18 (up 6.7%), finish 42.2% (up 3.8%)

2012-2013 — 45.4% through 18 (up 5.8%), finish 45.6% (up 6.1%)

2013-2014 — 47.1% through 18 (up 7.6%), finish 47.1% (up 7.5%) 

2014-2015 — 42.7% through 18 (up 5.7%), —

So, no matter how you look at it, this year’s FG% is lower through 18 games than any of the previous teams, AND their margin against their opponents is smaller as well.

Note, of course, that if you subtract the margin from our FG%, you can see our opponents are also shooting lower than any year except 2011-2012. So, this year’s defense is usually giving us a margin of safety. But not always.

Let’s hope that the offensive numbers go up at least a little, and that our defense continues to be strong. I’ll post updates on these stats as the season goes along.
