At first I thought yes then I saw your lineup and thought no then I saw your pitching and thought C.J could be a real asset especially when Alberto starts hitting again. I would accept it seems you have some offenese to give for some much needed pitching
I'd do it even if Wainwright replaces Wilson, but I'd certainly try for Wilson. Stanton will still hit 40 bombs. Dunn can't be worse than last year, but that doesn't mean he's back to his "old self" -- really, he's not. He's a human fan.
Did you mean Jordan Walden (LAA) instead of Branden Walden? He just got demoted to set-up man. Anyway, Guerra is apparently getting closer to losing his closer job. I'm not so sure about that, but you've got enough closers.
I would take Stanton over Dunn or Kendrick in a heart beat. I'm not very concerned about Stanton's start. I would ultimately do the deal, even if it's Wainwright instead of CJ Wilson, because you get Stanton.
So you're doing the streaming thing but locking down SV for pitching. Do you even care about getting back a CJ Wilson or Wainwright? I think the key here is to get Stanton in order to improve your power categories. You've taken a potential major hit with the death of Carl Crawford. Finding a decent 2B will be difficult. I would forgo receiving a SP and try to prevent losing Kendrick while acquiring Stanton. Give up Dunn, Willingham, any SP, or an elite closer (or multiple) since you can find saves throughout the year.
