Massive threads are fun and the different threads would oftn end up talking about the same stuff.
I'm not saying individual threads for each player, just limit it to position. Suppose the Nats don't re-sign EJax and the ensuing SP thread would be like this:
2013 Nationals SP offseason thread:
2012 Rotation - Stras,Gio,JZimm,EJax,Det,Wang,Lannan (Gorzo). Bunch of stats showing each.
FA - EJax, Grienke, Haren, Lohse, etc. Bunch of stats showing each and compelling arguments for why said pitcher would fit here.
Trade targets - Price, Shields, Lincecum, etc. Bunch of stats showing each and compelling arguments for why said pitcher would fit here and what the Nats would have to give up to trade for one of these guys.
Internal options - Lannan, Garcia, Meyer, etc. Bunch of stats, ages, development, reason for internal candidacy and repercussions of using internal options.
