Hmmmm...I know the national media are all ripping on Arizona on this one, but I think the Braves gave up a solid group for Upton.
Justin Upton and Chris Johnson
Martin Prado, Randall Delgado, Zeke Spruill, and Nick Ahmed
Depending on your source, there are some saying the Braves made this move without give up a single top 5 prospect (though Sickels has Spruill #5 and Ahmed #7 in the system). I just really think Martin Prado is an underrated player for what he brings to the table. He's very solid defensively at multiple positions, has a good bat, and he's a great clubhouse guy. I also like Delgado more than most, seeing him as being a very solid mid-rotation guy for a long time.
All that said, the Braves just got Justin Upton. The "What are you Up2" tweets are annoying already, but I do like the "Up, Up, and a Hey" comment on the new Braves outfield. The NL East will be fun to watch next year.
