Making Sense of Joba's Inning Limit

The problem with the inning limit, estimated at 150-160, the Yankees have imposed on Joba Chamberlain for the season is not the number of innings, but that there never seemed to be a plan for implementing the limit. Did Yankee management really think that starting Chamberlain every fifth day for half the season and every sixth to tenth day for the second half of the season was a good idea? Did they really think that this was a good way to get the most out of him in the post-season? On August 1st, Chamberlain looked like he could be the Yankees number two starter in October. Thus far in August, he has pitched his way into the number four spot in the post-season rotation; and there is real danger the Yankees will not want to use him at all in October.
