I would totally take it.
Chapman is good, but until he gets his control a little better, will remain mostly a setup guy. Arencibia has the potential, but we haven't seen it yet.
Avila isn't going anywhere and Granderson will have better stats than last year.
I would hold on to Drew. He's poising himself to have a terrific year.
Pull the trade for Avila and Granderson with no regrets, especially when playing @ Yankee Stadium.
