Apparently, Shelton is eligible for C in some leagues. I only play w/ Yahoo, and my 2 leagues on Yahoo do not have him eligible. I could *really* use him at C in my deep keeper league as I've had to go w/out a catcher while waiting for J Lopez to return (or risk dropping a good rookie keeper as my league allows keeping everyone who doesn't become an official real life FA). I did try a little spot starting at C off the waiver wire for a little while w/ guys like Zaun, Fick and Doumit, but none of them get consistent playing time or produce consistently enough to be worth the roster space right now.
If only I didn't have so many hurt guys taking up roster space + DL slots, eg. Nick Johnson, Beckett in addition to Lopez, Drew, Bonds. If it wasn't the kind of keeper league that it is, I'd be more willing to drop a rookie like Dan Johnson or Swisher or even Bonds or Byrnes, whom I grabbed after the trade. For now, I need them to fill in for NJ and Drew in platoon fashion.
