I don't understand why you'd make this trade at all.
What McCutchen has shown this year, is that he's at least equal to Braun, and moving forward in a keeper league, I'd prefer him to Braun based on age. Upton and Lawrie are both exceptional keepers as well. The Yankees did not believe in Austin Jackson, and I am not in his bandwagon yet either. Halladay is in his age declining years.
Certainly if you removed McCutchen from the deal, I would suggest trading Lawrie and Upton for Braun. I don't know if that would get the deal done, but in no manner should you trade McCutchen.
