I've been very critical of Joe Morgan's work as an announcer and writer for ESPN and ESPN.com, but there is absolutely no denying his greatness as a baseball player. In fact, I believe Joe Morgan is one of the most underrated and under-appreciated players in baseball history. Looking up some of the numbers for this article just hammered that point home with me.Consider that, in 1975, he hit .327/.466/.508, led the league in on-base percentage, OPS, walks and OPS+, ranked among the top 10 in the league in batting average, slugging percentage, runs scored and stolen bases, won a Gold Glove at second base, and was the MVP of the National League. Adjusted to current levels of offense, Morgan hit approximately .330 with a .470 on-base percentage and a .570 slugging percentage, while stealing 67 bases at an 87% clip.And then he went ahead and did even better the next year, hitting .320/.444/.576 while leading the league in on-base percentage, slugging percentage, OPS and OPS+, ranking second in runs scored, RBIs, walks, extra-base hits and stolen bases, and winning another Gold Glove at second base on his way to back-to-back NL MVPs. Translated to today's levels of offense, that works out to around .325/.455/.660, which is absolutely amazing.
