McCann for Reyes

I'm real weak at catcher.  Head to head 10 person league, currently in 2nd place.  I have Ryan Doumit.  Someone proposed Brian McCann for Jose Reyes.  I have Rafael Furcal as my other SS. Have been using him as a utlility guy mostly and starting Reyes at short.  I have Kemp, Ethier, and Reynolds who have been puttin up pretty damn good power numbers.  Tough decision. 

Offensive scoring is standard.  Also have Ryan Zimmerman who's been plauged by a bullshit hammy injury.  My problem here is, I already have a lot of power on my squad.  Do i want to sacrifice Reyes run production and steals? 

pulled the trigger...thanks for the advice

In a one catcher league, I prefer Reyes.  In a two catcher league, it's really close.
