Unlike Plouffe, you can draw a line in the sand the day Dozier changed his mechanics with Bruno. After that day, he was a different player for the rest of the season (and a .678 OPS over a month doesn't change that, that's still way above Dozier's 2012 and early 2013 numbers). Dozier didn't get hot for a couple of months and hit a ton of homers like Plouffe. He started taking more pitches, he started walking more, he started striking out less. Does that mean Dozier is going to remain the player he was post-May of last season? No, absolutely not. But it means he has a better chance of remaining a very good player because everything about him changed as a hitter and maybe even more importantly, he looked like the player he was in the minor leagues. That didn't happen with Plouffe... Trevor just started hitting a bunch of homers and once those homers dried up, he was back to being a marginal player. With that said, I believe Dozier's power numbers will decline this year. But given how he's walking more, taking more pitches, and putting more wood on the ball when he does swing, that's a much better indication that his change is for real and not the result of getting lucky on a handful of bad pitches over a two month stretch.
