He wouldn't commit to the 160 limit b/c it's a media creation. Rizzo has never said Stras is on an explicit innings limit.
Yeah, sure he's not. Just like ZNN wasn't on a 160 inning limit. See? He pitched 161!
He's going to be limited somewhere in that neighborhood. If he has to make one extra start to get to 165 or so to qualify for ERA trophies/CY, etc. then so be it, but there's no way he goes far north of 170.
