I can't disagree with that list too much; I have the same 1-2. Prime Pedro was the craziest shit ever; he did all of that during the height of the steroid era, too, and I'm 99.9% sure he wasn't juicing. Kershaw is nuts today but hasn't proven himself under pressure in the post-season yet. Still, I'd say that he's definitely in there. I'd probably put Smoltz in at #5 just for his post-season numbers, which are insane. If he keeps it up, Madison Bumgarner might crack the top 5 too- that shit in the WS last year was fucking nuts. I remember watching the last game and when he came in, I knew it was over.
CC is definitely overrated. Dude should have signed with a NL team, could have won a lot more games, though.
