I know there was a lot of skepticism of him. Whether it was implying it was all PEDs or a lucky year people were willing to write him off.
I don't believe he's as good as he has been playing. In the past he went on some huge hot streaks. But I do think he's for real. Last year he actually got better as pitchers adjusted to him. And this year he has been phenomenal. I figure a line of 270 400 600 is entirely in his reach. Maybe 40 to 45 HR's. With solid D in RF he is one of the best players in baseball.
IMO the whole PEDs discussion was a joke. If it was that easy to go from 14 or so homers to 54 by taking PEDs wouldn't every other aspiring player take the same concoction? Further, not only did he show huge power potential but in the September of 09 he started to break out in a big way. This doesn't mean he hasn't taken, I have no idea who has.
From what I have read he worked all 2009 on eliminating the hitch in his swing and didn't show results until the end of the year when it became natural. There are quite a few star and even HOF players that had similar problems and needed to adjust. As much as we tease Joe Morgan about some of his sayings he has been bang on about several players with regards to this. If a player has a hitch in their swing MLB pitchers can easily throw off their timing.
