To clear things up, I entirely believe that Martin Brodeur was one of the best of the best goaltenders. I don't "think less of Brodeur" because of the teams that he played on.
However, I think that any reasonable person would agree that if you gave Stephane Fiset Brodeur's opportunities (and vice versa), Fiset's career would look better and Brodeur's career would look worse.
Or Ken Dryden and Gilles Meloche.
Or yes, Patrick Roy and Craig Billington.
Because context matters. Would Fiset have Brodeur's exact career (and Brodeur have Fiset's exact career) if they were swapped? No, absolutely not. But would it have zero impact? Again, no.
Context is the fun part, too, because if we could definitively rank the best players in hockey history with a copy of Total Hockey and a calculator, then what would the point be? (It's somewhat ironic that people denigrate so-called "advanced" stats because you "can't use numbers, and have to watch the game" to rank players, but still use their chosen numbers to defend their case. Not you specifically.)
I'm a student of goaltending history, and I'm a fan of Brodeur's. I'm a fan of Fiset's. Roy's. Meloche's. You'd probably find it weird to watch a game in the same room as me, because I usually root for both goalies. With that said, I'm sure that I have biases. We all do. This sort of thing is difficult, and people aren't going to agree. But that's okay - this is a discussion forum, and discussions make it interesting.
Context matters.
This is a really simply stated, yet very important post. You're good at those.
And thanks for saving me from all the back and forth with Blueton. I didn't want or need that.
Full disclosure - I think Brodeur is, at worst, the 6th greatest goalie of all-time.
Brodeur did the most with the situation given to him, and no one can fault that. It is no different than Ken Dryden.
It's not like Ken Dryden, or like Roy. Dryden had a highly advantageous team situation and he responded by being voted/considered/named the top goalie in the league six times and posting the kinds of personal numbers you'd expect from a guy who was awesome to begin with, and also had those advantages: top-3 in sv% 6 times (1, 1, 1, 2, 2, 3)
Roy's team situation was similar to Brodeur's - not in style, but in terms of the quality he was surrounded with - and he took those advantages and he turned it into a career where he was top-5 in the league in sv% as often as he wasn't (1, 1, 1, 1, 2, 2, 3, 4, 5) - not to mention three Conn Smythes.
I'm not saying Dryden is better all-time than Brodeur, either - a full 15 years of being, at worst, the 7th best goalie in the league, half the time top-3, carries more value with a longevity guy like me, compared to being most likely a top-2 goalie for 6 of 8 full seasons. But at their respective peaks, I don't compare Brodeur's situation and results to Dryden's at all. Dryden transcended his advantages and posted results so strong no one could question him. Brodeur didn't always do that, and that's why some question him to this day.
