What are you talking about, he's "right on track"??
In their second seasons, Trout improved by 290 points of OPS, Cabrera by 100, Stanton by 60, Harper by 37. You can blame last season's relatively low improvement rate on him being injured, on him being young, etc etc etc. There's no excuse this year. Those 3 guys averaged an OPS of like .920 in their age-21 seasons. If Bryce does that this year I'll be ecstatic. If he doesn't, and puts up something in the mid to high-800s again, it doesn't make him a bad player. It just lowers the chance that he'll be one of the best hitters in baseball at any point in his career, which was the expectation coming in.
