It's interesting. He's a lefty whose IP and CG are off the charts, insane, video game like totals. And the amount of years he did this is too.
But this total Ks and K rates aren't really anything special at all. And, if you look at his stats that are adjusted for park, league, and compared to a league average, they're not ridiculous either.
Incredible pitcher for his time, but I feel it's doubtful he does that against today's hitter. Who knows?
