They usually say that the team gettnig the best player wins a deal, and Posey is the best player.
However, IMO your getting #2,3, and 4 in the deal.
Vetters is going to be an animal for years to come, Marcum is a nice SP, Soto OK.
I think Anderson could turn into one of those SP who can never stay well, I drafted him and regret it now.
Perez, I assume Chris Perez, is a very good closer, but will not be in Vetters class as soon as Vetters gets a little more experience. I realize Vetters not closing yet, but he will be for someone.
You do lose out on some saves, but the return is there for this year, and even next year I think this might still be OK if Anderson pans out how I think he will, lots of visits to the DL.
So, I would do it, helps this year, probably breakeven in the future.
Thanks for your help on mine.
