This is an ongoing analysis project to quantify the effects of analytics on the big four US professional sports teams. The ESPN Great Analytics Rating in 2015 http://www.espn.com/espn/feature/story/_/id/12331388/the-great-analytics-rankings is used for the team analytics ratings. I had to give the Las Vegas Golden Knights a rating of 4 since ESPN never did the rankings again and the NHL decided to expand. The presentation has been presented at the 2017, 2018, and 2019 INFORMS Annual Meeting and at several MORS Critical Skills for Analytics Professionals (CSAP) courses. It was also presented for the NC State Sports Analytics Club in March of 2019 and at a Meetup.com event in April 2019. www.Spotrac.com is used for salary data. Cash salary is used for NBA, MLB, and NFL. The cap difference is used for the NHL. Teams are ranked from 1 (paying highest salary) to the last team (paying the lowest salary).
