In 2006-07, Martin Brodeur set a new NHL record for wins in a season with 48. This was hyped as a huge achievement for Brodeur, and yet another sign of his greatness. The problem is that even laying aside how useless wins (a team stat) are in terms of evaluating goalie play, a closer comparison of Brodeur's situation to Parent's shows that this record is not very impressive at all.
The biggest difference is of course the introduction of the shootout. Brodeur won 10 shootouts, the most in the league, meaning that he won just 38 games in regulation time or OT. Not only is that not even close to Parent's total of 47, it wasn't even enough to lead the league, as Luongo posted 42. Brodeur was also actually worse than league average in shootouts (.667 save percentage, 26th best in the league). Luckily for him, his Devils teammates had a 43% scoring proficiency which meant Brodeur was awarded the "W" in 10 out of his 16 shootout contests. He also won 3 games in overtime, which was not in effect in the 1973-74 regular season.
Brodeur's record was 48-23-7, or 18 games above .500, despite his team scoring just 21 more goals than they allowed with him in net. This may indicate clutch play, but more than likely is largely the result of luck and effective team defensive play while holding a lead. Brodeur was 30-14 in one-goal games, 20-8 not including shootouts.
New Jersey also had an extraordinary ability to score late game-tying goals, scoring 7 times to tie the game in the final minute or with the goalie pulled. Brodeur played in 5 of those games, which resulted in 4 additional wins from his teammates essentially bailing him out.
Since the season is longer these days, Brodeur played in 78 games to Parent's 73. The result is that Brodeur lost over twice as many games as Bernie, and his winning percentage was .660 compared to Parent's .736, even with the benefit of extra points available from shootouts and OT wins.
In summary, Bernie Parent's win record is much more impressive than Martin Brodeur's. Parent won 47 games in regulation to Brodeur's 35, despite playing in fewer games. If Parent had shootouts and overtimes, he likely would have won something like 55 games. Brodeur "won" more games because of the shootout rule (where his teammates made up for his average play) and because his teammates were proficient at scoring late game-tying goals with him watching from the bench.
But really, when you get down to it, Brodeur won a pile of games because of shootouts, Parent won a pile of games because he played for a dominant multiple-Cup winning team, and it doesn't really matter who won the most because it's a team stat. This whole charade just illustrates the pointlessness of using wins for evaluating goalies.
