Rangers Willing to Move Callahan?

Wow.  According to Steve Zipay, the Rangers may be willing to move Ryan Callahan.   That's a little surprising.   Sure, moving Dan Girardi would seem to make sense if they don't have room to re-sign him or would rather get the assets, but Cally?   Logically, trading Cally might make sense, depending on the return.  He gets hurt a lot, and if they could get a first rounder and someone with more reliable health, it would probably make more sense than overpaying to keep him.  That said, he's a totally homegrown Ranger, has worn the shirt proudly, has played terrifically, is the Captain and has all sorts of intangibles.   Those kind of guys tend to stick around at least until their late thirties, right Brian Leetch?    But seriously, unless something else is going on, I really don't see it happening.  It will be hard enough to part with Girardi if they do that.
