Let me 1st say that I am not saying they should... I'm just throwing this out there to see what you all think.
Johnson currently sits 4th in the league with a .931 save %, T-4th in the league with a 2.00 GAA but has only started 10 games and has a 7-2-1 record. He was/is a big part of why the Penguins are where they are right now this season, picking up the slack when Fleury wasn't playing up to par... but now that Fleury is playing like Fleury plays, it doesn't look like Johnson is going to get much playing time.
Last season Fleury played 67 games and probably won't get that this season... but barring an injury, he'll see the lion's share of starts from here on out... It kind of seems like a waste to have a goalie that has been as hot as Johnson is... sitting on the bench... but, it's also awesome to have such a good backup to give Fleury a break, make the occasional start and/or come off the bench when Fleury gets shelled.
Maybe Johnson's value is at it's peak with what he's done since he joined the Penguins... there is probably at least one team out there that would be willing to at least give him a shot at being their starting goalie and maybe the Penguins can pick someone up that would help them out.
Ultimately, I don't think it's something that's possible... the Pens are basically capped out and trading away Johnson would only free up whatever's left of his $600,000 salary, and I doubt the Pens are going to get someone worth while that only makes $600,000. Maybe they could package a Comrie with Johnson and get a decent player to help. Also... I don't really see many holes in the Penguins where they really have a big enough need to get rid of the cheap and reliable Johnson.
So, I'm pretty sure most answers to this will be no, keep him and there was probably no point in making this post. But, it's here anyways. Any thoughts?
