I'm TRYING to be a scout? How many guys have you gone out and evaluated in person?
You are trying to prove an agenda with a small sample size, something you would lay into other people about, just because you want to say that he's not the prospect he was a year ago, which is stupid in itself because you do not knock prospects down lists because of performance at that level and age.
He still grades fine with power, his hit tool is still fine, his plate discipline is still good. Like 90% of prospects he had to deal with advanced off speed offerings he wasn't used to seeing at a young age, that's not making excuses or ignoring anything, it's just not enough of a story in half a season to re-evaluate a player.
So what are you assessing by his half season in AA? Because it sounds like you are hedging your bets and saying he may bounce back just fine, but at the same time trying to say that you are worried about him as a prospect after that half season. You can't have it both ways.
Put it out there then, what you do you think he's going to do as a player now after this half season that you may or may not have thought about him before this season?
Actually, I am evaluating this trade and the bottom line is, Castellanos can not be worth as much right now as he was worth last year. That doesn't mean he isn't a top prospect or can't be good going forward but its foolish to ignore the issues he had this season.
There has to be more doubt in your mind right now vs last year.
Plenty of guys have looked great in the lower minors, gotten into the upper minors and not been the same player...and, many times, it is because of the exact things I am concerned about...lack of walks, missing bats, etc...Those are issues...for you to act like they aren't is wrong.
To answer you...I have no idea what he will do next year. Since I haven't seen him play, i can only go by what he actually did and what he actually did, against higher level pitching(albeit at a young age) gives me at least some level of concern that didn't exist before.
He likely will be fine this year. He likely still has an 800ish OPS season, which would be very good for the eastern league, especially at his age.
But if you are asking me about trading for him, I am saying that I would not be willing to give up as much for him today as I would have a year ago and that is what this thread and this discussion is about.
