Again, I'm not saying he's a good player. I don't think he's better than a Kindl/pressbox/7D. But that's literally infinitely more proven than Turgeon is. Which is my point.
Turgeon isn't a particularly great prospect (which isn't to say he's not, possibly, a good prospect), and I doubt anyone thinks he's a likely or possible 1/2C. So it shouldn't be overly surprising that a guy who played 1/4 of the season in the NHL, and only apparently got passed over last season for Marchenko because he's a LHD and Marchenko is a RHD, is rated higher.
But again, after about the top 4, our prospect pool kind of sucks, right now. I don't see any reason why a good argument couldn't be made for any of the next 11-12 guys over any of the other guys in that group. I'm just trying to tell you why the board is likely still high on a guy like XO.
