Anything that involves prospect values is going to be fairly subjective, and that site in particular probably isn't as responsive to recent health/performance trends (although there are limits to how much these guys values are going to shift over smaller samples too). Diaz and Blankenhorn probably deserve a boost from this season, but the other guys are far enough away, or still have enough performance questions, that I don't think these ratings are that far off. As for Vasquez, it's hard to value all those years of control. You might be right to only offer so much, but the Pirates might be right to reject it right now too -- he's controlled for so long, they can probably get a similar return a year from now if they want. Edit to add: I think the fact you can make a Vasquez deal work without Lewis, Kirilloff, or Graterol show the reliever discount, as compared to starters.
