I'd like to see some evidence that it's becoming more bimodal. Your baseline year of 2014-15 had 5 teams between -10 and 10. This year has 5 teams between -10 and 10.
You haven't addressed the increase in ENG (397, not prorated this year v. 284 total in the baseline year) where losing teams couldn't care less about allowing a marginal goal, and the fact that the standard deviation of winning percentage hasn't appreciably changed since 30 years ago.
