I don't think Bouchard's skating is a true weakness. He's no pylon. In general, I think he'll be a very good skating defender, one with very good size in addition to nice offensive ability. If you compare his skating to that of Dobson, Hughes and Boqvist, then you have more of a point, but two of those other guys are pretty much just offensive defenders. Bouchard I think would have good offense and more. So, I think Bouchard compares favorably to Hughes and Boqvist, even without the worry over size or possible multiple concussions.
Further, I would note, when comparing Bouchard's skating to say that of Hughes, that while Hughes' skating would kind of give you the neat option of putting a fourth forward on the ice, he likely wont make a first pairing in the NHL for his defensive ability. Hughes I think would be almost entirely offensive at the NHL level. I also think, like Bouchard's skating, Hughes' offensive talent isn't such a strength when comparing him to Bouchard, Boqvist and Dobson, who will all strengthen a team pretty nicely offensively in their own ways. With Boqvist, I believe you would have a similar situation to that involving Hughes, although maybe not quite so extreme.
Where offense is concerned, I think it's a neat luxury to get great offense from a defender if you can afford it because you already have enough good defense, or if you are getting good offense from a guy who also defends well. That doesn't remind of the situation that the Wings have at all though, not in any way, shape, form, or stretch of the imagination. That's one reason why I would go Bouchard over Boqvist and Hughes, I think he brings more than just offense.
So, I would be happy to have Bouchard, but still I'd probably trade his better offensive talent for Dobson's better defense if the option is there on draft day. Dobson is bigger, can defend well, contribute nicely to the offense, and skate his a$$ off. Notwithstanding, I don't think the Wings are putting up much, if any, smokescreen around Bouchard though. I think Bouchard's got a lot of what the Red Wings want plus some impressive intangibles.
