He definitely puts in the work, but to some degree his rankings are for tv and clicks.
Craig lost a bit of credibility for me back in 2012. It was the start of the 12-13 season and I saw him in Halifax. One of the first games of the year. Mackinnon had a great game. I asked Craig who he would take between Mackinnon or Jones, his response was "Mackinnon, and it might not be close"
Fast forward 1 week and it was tsn/bob pre season draft rankings. 10/10 scouts chose Mackinnon at #1. Then comes buttons list....Jones at 1. Seems to be the network instructed or heavily hinted that they needed to drum up some "Mackinnon vs Jones " hype and having a unanimous #1 would be bad for that. Or maybe he lied to me because I was from Halifax, but I doubt it.
I don't doubt he views a lot of hockey, and he puts in the time. I maybe question his methods of evaluation sometimes, but mostly I question the authenticity of his rankings and feel they are to some level used to generate clicks. Just my opinion
