You have 100 M&Ms, 32 people. 10 of those 32 people have 60 M&Ms. The remaining 22 have only 40. That is meaningful. I know it's not perfect, but it's a quick analysis.
I measured top and bottom, because it's logical to assume, more often than not, that good teams will have top 10 stats in seemingly important categories and bad teams, bottom 10. You're more than welcome to measure top 15 and bottom 17. I didn't have enough time for that.
I agree, it would be interesting to see a couple more years, too.
