Bernier is available from Detroit, he's been really good behind a really bad team, he'd likely do just as well behind a really good team. Doubt the price would be high on him. Campbell gets has a good opportunity here but if the team plays well & he struggles or goes down they gotta at least look into Bernier & a partner for Andersen.
In this case dump Andersen for whatever you can get & pay
< 2nd for Bernier. We just need a reliable consistent goalie, he's low risk medium reward and that's good enough. It'd be easier for him here than in Detroit. His lowest sv% and games played since being a starter/tandem goalie was .904 in 35gp for Detroit.
Jonathan Bernier Stats and News
If Campbell plays well then maybe they should keep Fred, or maybe it would just make him expendable. If they're trying to improve their roster Andersen has a big fat 5m and has been costing them game after game. Bernier/Campbell I'd be comfortable with and the saved cap space can be used to improve the team in front that looks promising. Just play the odds, & the odds are looking like Andersen isn't close to getting it together and another goalie is. Sometimes goalies have bad years and good years, Andersen is having a bad year, much worse than last year which I considered a bad year for him. I think he'll be better next year at some point, maybe the year after but that doesn't matter to me or the Leafs. He's gone after this year, this year they have a great chance to make a playoff run. Leafs have the luxury that he's on a 1 year deal (pending UFA) and have a good backup... take the chance (with good odds of a better goalie currently) on Bernier and the cap space to make deals to improve the team further.
Leafs are playing blackjack and the team's a 10 & Andersen's a 2, odds are they should hit given Benier is available.
In all honesty Jack Campbell is this teams best hope this season. Gibson is having a bad year and a team aquiring him could buy low and probably have a good goalie for most of the 6 year deal but this year he sucks and probably will continue to as well, or not be that great, Carter Hart too. Leafs goaltending needs to be good this year. This year Fleury is a great goalie & he'll likely be Vegas's guy over Lehner.
