i don't think the shutout record will be touched - i don't think the nhl will let defense rule like it did during brodeur's prime. in 10 years, it's going to look just as insurmountable as gretzky's points record does now.
There is just so much to it. This record is helped by Brodeur playing on a team that plays such a defensive system. It also helps that Brodeur played under such an amazing GM who built such a strong team year in and year out. Obviously Brodeur is a gigantic factor of the system being so good and the team being so good. But I think Greg said it well in his piece, don't think for a second that Joseph is getting 104 shutouts for the Devils.
Even if there is a goalie as good as Brodeur out there, he would need to play for a great defensive team year after year. He'd need to stay healthy every season. Even then it be so hard with the all the rule changes, although I think that is overblown. Scoring is once again down and there have been plenty of shutouts around the league.
