I don't see where canucksfan said "Dryden is way better than Brodeur." He said "At this point in his career there is no way he is better than Dryden." There's a world of difference.
I agree that longevity is part of greatness. But Dryden only had the most successful eight-year stretch in the history of the sport. And I would have loved to see what Dryden could have done over a long career, too. Hmmmmm, let's see. A flawless, technically sound, efficient, some might even say effortless, goaltending style. A winner's mentality. A great work ethic. Maybe the most poise and focus of any goalie, ever. Likely the best when facing 15, 20 or 25 shots a game. Yep, even better than Brodeur.
Dryden's stats get worse in the playoffs? Funny, last I checked, he won six Cups in eight years. Stats? Who cares about stats when you win six Cups in eight years. And he won a Conn Smythe. I don't care about GAA and save percentage in the playoffs. I care about one thing: winning. And in every Cup run, Dryden won the maximum 12 games. Need a big save? Dryden got it.
I'll take your word that Dryden's backups had a better winning percentage than he did. But your statement couldn't be more loaded. After all, I'm guessing those back-ups probably played against the Vancouvers, Washingtons and Kansas City/Colorados of the NHL, while Dryden played Buffalo, Boston, NYI, Philly and the other good teams.
