You can swing on the overseas guys maybe, or guys like Castle/Williams/Holland have a lot of potential if all goes well, but there are no surefire stars, so it's all tossing darts at the board.

I think the benefit of guys like Sheppard or Clingan or Knecht is there are elite skills on display where you know *exactly* what you're getting-- instead of just swinging for the fences on a draft where the stars, if there are any, are likely to emerge out of the blue.
