Joe Posnanski has a story up at SI, which is basically a discussion with Bill James about Nolan Ryan's implementation of changes in regards to theories of pitch counts.
James is more favorable than one would expect...the sense that comes across is that teams have gone too far in the direction of being over-protective, with James expounding on more reasonable threshholds that should be set instead of the 100 pitch barrier.
An interesting read, well worth checking out...
