Re: 2014 Reds
That's what's so exciting about this team - it doesn't appear to be falling apart anytime soon.
Hopefully Choo can be replaced by Hamilton.
Hopefully Arroyo can be replaced by some combination of Leake/Corcino/Cingrani
I don't look at Masset as needing a replacement, although Ondrusek and possibly Lotzkar or Cingrani could easily replace him (and/or a veteran major leaguer).
Barring major injuries, there really doesn't appear to be any major holes that need to be filled via trade for the next 18+ months. I'd look to extend Latos and possibly Bailey. By the time one or more of the SP is eligible to leave via FA (not until 2015 at the earliest), one or more of Corcino/Cingrani/Stephenson should be more than ready to step in.
