They certainly could have started Joba in the rotation and then diverted as his innings cap came about. Also, Halladay is not a good example. Halladay was a 1st round pick, but his production prior to getting called up to the bigs was marginal to say the least. His production prior to callup would have warranted a bullpen spot. Something clicked in 01, after he had a 10+ ERA in 67 innings in 2000 and split the rotation and pen duties in 1999. The bullpen did nothing but screw with him. As for Johan, he is very similar. He was awful in the minor leagues, enough so to be placed in the Rule V. It took 4 yrs of coaching, frequent demotions and work on locating his changeup before he became a good starter. Neither of those guys had the minor league pedigree of Hughes and Chamberlain and both of them were given chance after chance to learn the ropes at the big league level because their teams were awful. It paid off in the end, but in NY, it doesnt work that way. The only way they will get better is to pitch more, not less. And by moving Hughes to AAA, he will be afforded that necessity.
