This pretty much squares with what I recall - he had that complete game on 90 pitches or whatever and some other really good starts and then he's had some total meltdowns.
He's the prototype of what I want in a number 5- he threw away a bunch games, that's why he isn't a 1,2,3 or even 4, but he was absolutely dominate when he was on, unfortunately, he doesnt want to be paid like a 5
