Looks like I was wrong, Lemaire actually only coached Roy for a whopping 20 minutes of his career. He retired in 85 and returned to coach New Jersey in 94.
Brodeur's 03 run is stellar, but it's not better than 86, 89, or 93; it's right there with 01 and I wouldn't be upset if someone said it was a bit better.
The Habs were not trapping like New Jersey. It was a collective effort from their players (especially in 93), they definitely weren't a structural boa constrictor like NJ.
Brodeur's puck handling and the trap indeed played a role in his sv%, and he does get credit for being a workhorse (However, I don't think that's a good explanation for his numbers being lower, and actually suggests it's a bad thing. The Devils weren't making the playoffs by the skin of their teeth, he could've very easily taken games off if it actually impacted his performance). All that being said, it was very much a two-way street with Brodeur and NJ's system, and outside of his GP and win totals, nothing about his resume suggests he's better than Roy and Hasek let alone on their level. I'd actually slot him right in with Belfour as far as peak performance is concerned. He gets credit for his durability and outside factors, but that's what separates him from a Belfour/Lundqvist/Price, not what puts groups him with Roy/Hasek.
Also, if Brodeur was robbed of a prime season (which I can only assume would matter if this was about trophy counting), then it all evens out by that logic considering Luongo was robbed blind in 04 (Turco too more than likely but I won't even get into that).
