Steven,
Why do you think they chose Davies over Quenneville?
Honestly, you need someone better than me to answer that.
I love Quenneville. He's dynamic offensively, and deceptively strong and physical for his 5'9" stature. He can really skates and has exceptional instincts for when to join the rush.
Of course, like most pundits, I was able to see a ton of footage of Quenneville, playing for Medicine Hat of the WHL. I barely saw any of Davies' footage, as USHL film is difficult to find. I have a contact or two who scout the USHL, but I normally only ask them about higher profile prospects -- it's why I was so high on a player like Andrew Peeke or Wade Allison.
Since Davies was not heralded too much, I didn't ask for any info on him and knew nothing about him entering the draft except that he was small but led the USHL defensemen in scoring.
The Devils clearly sent scouts to watch him play, and clearly liked what they saw. Shero and Castron both have a good track record of scouting the USHL, the most up-and-coming developmental league in the world (outside of Finland, ha). If Shero and Castron are all-star pro scouts, consider me like a fourth-line banger scout in the AHL. So, although I personally loved Quenneville, I'm willing to take their word for it on Davies.
A final note on the USHL: their prospects are universally ranked lower by the media scouting bureaus than they should be. Why? Easy. The CSS or ISS will have several scouts for each CHL conference, but few scouts roaming to watch the USHL, NAHL and all USHS. So, they'll have several scouts that have seen everyone on the London Knights tons of times, but far fewer scouts who have seen Peeke or Davies once or twice. When the votes come in for the rankings, of course they will be weighted for the players they were familiar with.
Thus, when the media looks at Columbus' #34 pick of Andrew Peeke and calls it "a reach" because he was not ranked that high, they are being asinine. I had Peeke as a late first/early second. So did Steve Kournianos (The Draft Analyst). He is the Steve Santini/Erik Gudbransen of this draft -- a big, mean, mobile and smart shut-down defensive defenseman.
In conclusion, if Jeremy Davies played this season for Rouyn-Nouranda or Kitchener, there's a very strong possibility he would be ranked universally in the top 100 and be drafted in the third round. He's got a few years to round out his game at Northeastern, and time will tell. As for now, I will drop my Quenneville hammer and back up Shero & Castron, because they are better than I am at this.
