Unsportsmanlike Conduct in the NBA Follows an Inverted U-Shaped Curve

Over at 538, Benjamin Morris asks "Just How Bad Were the Bad Boys?" The bad boys in question are the Detroit Pistons basketball team of the late 80s, who had a reputation for being unusually aggressive on the court. Did they deserve their reputation? To test this, Morris looks at how many technical fouls they racked up, a good measure of unsportsmanlike conduct. In fact, he takes a look at the total number of technical fouls for the entire league, and finds that the number rose steadily until 1995 and then started a long-term decline.

I promise this is just for fun, but I've overlaid another line against Morris's chart. Not a perfect fit, granted, but not too far off, either. I'm sure a few of you can guess what it is, can't you?
