That word, I do not think it means what you think it means. Soto has a track record of success that justifies excitement. Castro has a track record of success at a position where it doesn't take all that much to be really valuable. Colvin is not great. He's not a great building block. It might be great to have him around, although it might just be pretty nice. The point that is being repeatedly made, and repeatedly ignored, is that he is not great. He's an okay piece with some gigantic flaws to his game, the kind of flaws that can really hamstring an otherwise physically capable player. He had a great start to this season, when used sparingly, but the more he has played the more his numbers have dropped, and the more frequently he has made outs. If you want to be excited about him, go ahead, but I think the time for that was about a month ago. Over the past 28 days, his line is .244/.272/.500 with 20 K in just 81 PA, and only 3 BB. Aside from the surprising amount of HR, those are the types of numbers his minor league career more or less predicted. They aren't great.
