The "Irreplaceable Yankee"

Baseball Prospectus provides a free preview from July 21 to 27. Their in depth coverage is illustrated in an article detailing Jorge Posada's dire injury:

"There continues to be some question about how Posada's situation has been managed. He appears to have tried to play through it, with Joe Girardi—the former Yankees backstop who started ahead of Posada earlier in his career—not 'allowing' Posada to play through pain. Yet Posada told the press that "it hurts to throw, and I can't catch like this" on Monday. He can hit, but if his or the team's insistence on catching has caused an exacerbation, it's clear that this was mismanaged. For a team willing to sign Richie Sexson, playing Posada at first base or designated hitter should have been an option. If Posada elects to have surgery, he should be able to return, though the impact on his throwing will be seen well into 2009, raising these same questions again.
Overall, Posada is truly the irreplaceable Yankee."
