The problem is that Marty has won 17 games and gotten 38 total points in 35 starts and Cory has won 14 and gotten 37 points in 38 games. It doesn't make sense and it's what screwed up Cory getting the games he should have been getting.
The other issue is that whenever Cory had a chance to run away with the job, he'd falter, Marty would falter slightly less, and we'd be at square one again. Hopefully next year this is no longer an issue, and Cory gets the 60 or so games he should be playing with his numbers. Without the recent slide, he's been one of the best in the league.
Well, there is also the issue of how often does Cory need to prove himself. Schneider had a stretch of 14 of 15 games or whatever of not giving up more than 2 goals. That's pretty sensational. He stumpled a bit, but what goalie hasn't? Imagine if every NHL starter's good play was reset after a few poor games. Pick any starter and I'll show you a number of bad games in close proximity to one another.
I'll go with Rask since many think he is a top 3 goalie in the NHL.
Dec 28th: 3 goals on 12 shots. Pulled after 1
Dec 31st: 5 goals on 31 shots.
Jan 4th: 1 goal on 37 shots
Jan 7th: 5 goals on 20 shots
Jan 9th: 3 goals on 18 shots. Pulled early in the 2nd.
He gets the start two days later and has a 26 save shutout.
If Cory Schneider had to prove that he wa sbetter than Martin Brodeur continuously all season, he has passed that test easily. Why he has to continuously prove it is a mystery to everyone around the NHL but people in the Devils organization.
