I made a trade where I gave up Oswalt and Vazquez to get Greinke. I have no regrets about that move. I think that was a great move for me. Somebody in my league wants Soria and Brandon Webb, and he is offering me Bailey and Markakis to get him. He has McCann who I want to back up Mauer. Should I make him an offer of Street and Webb for Bailey and either McCann or Markakis or am I asking for too much?
I would stick with his first offer. You have no need for McCann if you have Mauer. That's just greedy my friend. Take Markakis and Bailey (who will likely have 35+ saves this year), and walk away smiling.
