I always thought Castillo would be untouchable. So when the Reds put him out there I instantly began to come up with trade options. But come right down to it, I think this would become a futile exercise, because some get excited about the possibilities and others anxious about losing their favorite players or combination of both. I don't see FO making this trade unless they really want him and I mean really want him and in that case I wouldn't trust them making the right trade. I'm a firm believer of trading. Trading helps us to balance our 40 man roster and bolster area where we are weak at the same time thinning areas where we are overstocked. I believe every player have locked potential. If you are fortunate the team that draft a player has the key to unlock that potential. But many times they don't so trading that player, gives him the opportunity to find the right team that pocess the key to unlock that potential. Johan Santana is case in point. He came to the Twins as a good pitcher but when he found the key of the circle change up, he became an elite ace. How did the Reds come across Castillo? Castillo bounced around as a young prospect. Miami saw potential in him and had 2 opportunities at him, they all gave up on him. Reds picked him up for almost nothing and the rest is history. What's my point? My point is all prospects have potential and many can't see it and give up on prospects. Even if we can't unlock a prospect another team might. Also keep an eye open for players that we can unlock. I think this is the road that FO likes to take in FA. But still I'd like them to be more active in trading.
