You would get the best player in the deal, but... McCutchen is becoming a more and more dynamic player and there seems to be a lot of risk with Weeks, with his injury and performance.
Seems like a fair deal though...depends on your gut and what players you want on your team.
With Braun you know what you are going to get. I think McCutchen's ceiling is going higher. Teams will start pitcher smarter around him but if he's walked he's a big threat to steal bases.
Outfield help should be readily available on the wire, 2B production not so much...if you have a good back up at 2B consider it, otherwise I'd rather take McCutchen's upside over Weeks' injury risk.
