The only comment is that if you had to pick a position to take some trade bait in, its a shame that it had to be RP. I think you probably would have been better off with one or two more established and reliable starters and rolled the dice with one or two of the closers.
Lineup seems solid. Not the greatest I've ever seen, but solid. I'm not a huge Young fan personally. If Ethier is available (or can be had) I'd try to get him.
As of 8/4/13
