Oh man, I was shocked to hear this today! I loved McCurdy. His commentary on The Cult of Hockey was always spot-on, and, as others have said, he was not at all divisive, being the rare journo-type who could see all sides of it and not get lost in the weeds. He always put objectivity and the humanitarian-side above his own opinions (unlike most). Just came across as a very nice, humble person.
There are 2 specific things I really admired about him:
1) His writing and statistical knowledge. As those Cult of Hockey guys go, Dave Staples' articles are really poorly written (sorry to say) and his game-grades are often kind of wonky. Kurt Leavins is better, but nothing to write home about. But Bruce's game-grades were allways --- like 100% of the time, basically --- spot-on in my view, so obviously I saw the game much as he did. He did amazing statistical breakdowns of the Oilers that were often very revealing.
2) His encyclopedic knowledge of Oilers' history, and just his memory.I doubt there was a single human alive (besides maybe Sather?) who remembers as much detail about the Oilers from the late-70s to early-90s (and beyond) as McCurdy did.
If you want to learn what those days and that team were like, it's great to hear this interview with McCurdy about the Oilers' glory-days with Gretzky:
