The Rockies 75 pitch 4 man rotation has been universally blasted by everyone in and out of baseball. It all but assures Jim Tracy will be fired at the end of the year. That is the kind of idea you have laying in bed after a night of drinking and then you wake up in the morning wondering what the hell you were thinking.
While I do believe we'll see a 4 man rotation increasingly used by some teams (the Mets and RA Dickey being one), the pitch limit and 4 man rotation with the group of scrubs the Rockies has is absolutely a ridiculous idea. Jim Tracy should be (and will be) run out of managing baseball for that idea.
Pitching the 8th can occasionally be even more important than the 9th. A setup man coming into a 1st and 2nd, 0 out spot with the middle of the order coming up in the 8th is a far more stressful and crucial inning than the 9th when the closer faces the bottom of the order.
