I'm not quite sure what Cory being hurt last night has to do with who is the more viable long term goalie. And the "very weak second goal" was Steven Stamkos wide open in the low slot with zero pressure from any Devils player. Under no circumstances is that a weak goal, and if Kinkaid let that in you would say he had no chance. Kinkaid had a hot month or so. Every backup goalie has that a few times in their career. I don't care if it's Johan Hedberg, Scott Clemmensen, Chad Johnson, Michael Leighton, or Scott Darling. They all regress back to the mean sooner rather than later.
We know what Kinkaid is. He's an average to slightly above average backup. Cory has dealt with some injury issues, and that really impacted what was a strong start to the season for him. When he's on his game, he is absolutely Vezina caliber, and I'm confident he will have no problem getting back to his typical level.
