I don't know what he said about Dach, but overall I still think Bouchard is a very good coach. Probably has his ego inflated a bit too much but that's fine.
The problem with a guy like Bouchard is the same problem with guys like Therrien or Julien or Martin; they'll always reward hard work and effort over talent. Which is perfect, for bottom 6 Fs and 5-6th Ds. For your highly skilled players, you just gotta let them play.
which is why I'm not sure about him as HC in the NHL, but I'd take him back in the AHL (I know nothing about Groulx, nothing against him at this point).
