I haven't read every projection or mock draft by any stretch, but the ones I have seem to think Dominguez will probably be off the board by 15.
I've yet to hear of anyone who rates Ahrens above Dominguez or even all that close to Dominguez.
Neither have I. But it's kind of like with college football recruiting; there's a lot of consensus-bubbling when it comes to comparing a California kid and a Texas kid. I wonder how many scouts have made a specific effort to scout both players.
