Ozzie looked good, but on the other hand, the Devils are horrible this year. I'd wait for a couple more starts against better teams and see how he does there before declaring he's "back to form" and calling for a 1a/1b situation with Howard.
Osgood's really only had one rough start and even in that start, he was hung out to dry the majority of the time. Watch the video replays and look up the recaps if you don't remember. The rest of the time, Osgoods been solid. And while the Devils are horrible, they dumped quite a few shots on Osgood and many quality scoring chances. Osgood had to be great to hold them to the 1 goal. I'm not saying it should go to a 50-50 rotation yet either, but the idea that Osgood has played poorly this year is unfounded.
I'll say though right now, if Osgood keeps this up and plays at a strong level down the stretch, I would like to see him start in the playoffs. That is where he shines, and Howard stands to learn a lot from watching Osgood when it matters most. I believe in Howard long run, but I also believe in the developmental process. I'd rather go with the veteran and let the next guy learn how it's done especially after Howard's less than stellar run last year.
