From Baseball Prospectus writer Kevin Goldstein’s excellent article about the state of AL East teams’ farms systems comes this passage: "The Red Sox are anything but stocked when it comes to position players, particularly when it comes to infielders and catchers. Jason Varitek is one of the best catchers around, but the inclusion of Kelly Shoppach in the Coco Crisp deal is a little puzzling. Varitek, 34, is nearly at the scary age for catchers, and there (is) no obvious candidate to step in should something go wrong." Last year, the Yanks packaged Jorge Posada’s expected successor Dioner Navarro in the Randy Johnson deal, leaving the Bombers in a similar predicament in which the Sox find themselves. Both teams have gained great competitive advantages (the Yanks more than the Sox) from the performances of these players at this normally weak position. And now with both players in their mid-30’s and, likely, declining, the Sox and Yanks do not seem to have viable back-up plans for the post-Varitek and post-Posada eras. Is anyone else worried?
