He's in a slump and still OPSing .700? That's pretty good! And so Uggla's been hitting that way in June during a slump which is STILL much better than Young's entire season and 2B is a harder position to get RBI and HR from. You obviously aren't familiar with selling low, because you don't seem to realize that you're doing it right now.
As for him regressing, Young is getting older, so I don't trust that he'll be the same guy he was last year.
