Someone in that mainboard thread suggested that the ending of Brodeur's career (like his last few years of play, maybe combined with playing for another team) kind of ruined his legacy and made him a bit forgotten in the time since he's retired.
And while we could clearly tell we weren't watching the same Marty anymore by the end, he actually did hold up pretty well, especially compared to the current generation's goalies. Luongo is the only goalie since Marty to have held up as well as he did. He played well up until his last season in the league, but he met his decline roughly 1-1.5 years older than Marty was when he met his.
Even the guy across the river wasn't really holding up like he used to by 34-35, while Marty probably had arguably one of the best seasons in his career at 35, if not the best back to back seasons of his career at ages 34 and 35. Guys like Cory, Holtby, Rask, Bobrovsky, Price, were all noticably declining by 30 years old, if not earlier and many of them didn't see age 35 in the league or pro hockey. Rinne seemed to fall apart early, but then had one last reserve tank of gas that he used for about 3 years in his mid to late 30's.
Most of the guys sort of borderline Marty's generation (Nabokov, Kiprusoff, Vokoun) were either done with hockey by the age Marty started to decline or were even worse than he was by that point.
So my point is that he held up pretty well, all things considered, even if his last 4-4.5 seasons here were a twilight era. Roy retired before he could even have a decline season, but he played his last game at 37. Hasek had a similar ending to Marty, though his last several years were stronger than Marty's last several, but his last year was pretty bad and the last time he skated in-game on NHL ice was him getting yanked in the playoffs and losing his job to Osgood, winning the cup as a backup but never to play in the NHL again.
Belfour had that nasty 01-02 season that got him run out of Dallas and led to Turco overthrowing him, but seemed to have another tank in Toronto, similar to Rinne a few years back, but was a disaster coming back from the lockout, where he was 40 years old, to be fair. I've read Panthers fans rave about Belfour's year he played for them at age 41 in 06-07, but that was NOT at all a good season, especially considering he was right in between Luongo and Vokoun, who were both ELITE there, but the team was so awful it didn't matter. Belfour really wasn't NHL caliber anymore coming back from the lockout.
