Interesting topic, good article. What I would like to see is some explanation of why 400 constant and not 300 or 422. why K = 10 or 32.

The second part of the article is a bit of an abstraction to me, as I know little to nothing about American basketball. Also, if team ranked at the bottom as 25th has a record 23:5 - who is loosing? I would rather expect 5:23 for the bottom team. I see, top 25 teams, must be a giant league!
