I don't think it's possible to underestimate just how bad the coaching was post Seitzer and pre Brett. You could literally see, just as a fan, how off balance Moose, Hosmer, and Frenchy were. They were just hacking away, lunging at balls in the dirt and looked clueless. Their approach was shit, their mechanics were shit, and the results were shit.
I don't see that now out of Hosmer and Moose, and even Frenchy is squaring up better. We're not really seeing the results from Moose yet, but I think the mechanics are better and that results will come. I know it's been a about a full season of sub Mendoza line at this point, but I really do think he's coming around. Hosmer is starting to get around on the inside fastball, so I'm looking for his power numbers to start creeping up.
Anyway, my point is that the whole 'we're going to hit more home runs' thing was a horrible idea that set in a terrible approach that really ****ed these guys up. I think that's going to happen when you take guys who are probably 20 HR guys and try to turn them into 35 HR guys.
