why? If lots of guys did it but didn't lead the league maybe that shows you it was relatively easy to do in those years. sub 2 and leading league is cool oh, come on. as it is, 2 is just an arbitrary cutoff point that looks cool. it tells you just about nothing. i mean, if you want to look at what you're talking about, you just go look up who led the league in ERA+. hell, just last year arrieta had a considerably lower ERA (and better ERA+) but didn't lead the league because grienke happened to be lower.
