Depends - on him and on the rest of your team - whether his bat is good enough to be worth living with mediocre catching or some extra minus plays in RF.
I've used a guy who goes 12/26/66/66/44. We play in a pitcher's park, Portland, and last season we led the league in all major pitching categories while the catcher won a silver slugger.
This season he backslid a little, so I moved him out to RF and put a "real" catcher behind the plate. The new C has a CERA 0.9 runs lower, and CS% 90 points higher. (Could be the pitchers regressing to norm, though.)
In RF, the former C is playing maybe a little worse than the guy who was there before. One more error, one more minus play, ten points lower in RF.
