What does your analysis show for league wide xwOBA from year to year? I would presume we should see a trend upward considering the rise of offense across the league, so I would be interested to see how Freddie's increase compares to the league wide increase. E.g., how does my 10% raise at work compare to the 8% increase of cost of living.
Any thoughts on the factors that could explain the ~50% change YoY in xwOBA? Fifty percent seems like quite a bit to assign as random, but maybe baseball really is that random. Im not much of an econometrician, but is there a way to regress the years on one another to account for leaguewide pitching decline/improvement , or perhaps factor in minor league performance to account for players like Dansby that have initial struggles that may cloud there true talent level.
Overall, this is really impressive and I'm curious to read more about your work here.
