He hasn't been the old Johnny, that's for sure. More like Autoumaton Johnny. Step up, swing, groundball. He's not pllaying badly, he just doesn't seem all that into it.
Statwise, he's walking a fair amount right now, which is keeping his OBP at about the same level as last season. But where are those pretty little flare slap hits to left that always got him to 2nd?
I will go with the sold the soul explanation.
