So what they are showing here is the average attempts per team season by season. It looks like there's just a steady upward trend here related to our question. There's a couple of anomalies here. The ones that really jump out are these three seasons in the late 90s. That's because the actual three pointer line was pulled in to get higher scoring games, so people attempted more, but then it was put back to where it was originally. This was a shortened season. I'm not really sure what happened in the 2000-2001-2002 season.
