I like the idea of flipping one of your 1Bs, but I wonder what you would get for Butler. I'd probably shop him before agreeing to the trade for Kemp. I like Kemp in a 5x5 H2H league. 20-25 HRs with 30-35 SBs. Hard to argue with that, even if its 35HR, 100R, and 120RBI. 20HR/30SB from your SS slot is pretty ideal as well, even if it means passing on 30HR, 100R, 100RBI from 3B.
I also like Tex more than Kemp, but if you were to keep Zimm you would have 2 1B (with Butler) and 2 3B, so if you don't have any extra Util or CI spots you could be in a bind. If you have no extra spots, I could see myself doing the deal for Kemp.
I definitely like Kemp over Tex. I would do so in a redraft next spring, and the age suggests that's a long term shift. If CF is separated out from generic OF slots, this treads into "no brainer" status.
With Kemp, you'd have a worthy keeper in a format this shallow, favoring having elite, for sure.
For me, I roll those dice on Rollins. I would want to feel out something like Zimm/Rollins for Hanley first, but I'm a huge proponent of shoring up SS before UTIL. As good as Zimm's production is, at UTIL, it doesn't look terrible irreplaceable. Dropping from Rollins to a redrafted SS could be devastating, however.
Before I got the chance to formally offer the trade for Kemp I got an email from another owner in my league with Braun as a definite keeper and then a bunch of marginal keepers (Berkman, Jeter, Morales, Hamilton, Zobrist.) He said he would be willing to part with Braun for Tex and 2 of Wright, Zimm, and Haren (who I didnt mention I also have).
Since I wasn't going to keep Zimm or Haren anyways, I figure Braun for Tex/Zimm/Haren works for me. Figure Braun is a better keeper than Kemp right?
