If money was the only issue, it shouldn't be difficult to retain on Anderson. He's got 1 year left.
The Sens retained salary on Phaneuf. Anderson only has 1 year left.
I'd be surprised if there isn't a market for Anderson in some form. The upcoming crop of UFA goalies isn't great, and for a team in a certain spot, there'd be value in getting an expiring contract rather than having to commit term to a goalie. (For example, PHI if they wanted a veteran to take pressure off of Hart or to deploy if there are any growing pains in his sophomore season.)
I don't think we get a big return for Anderson, but I'd be surprised to find out there's no market for him.
It doesn't really matter if Nilsson has been better than Anderson this season.
Anderson is one of the leaders of this team, he will be the goalie until his contract expires or if he voluntarily asks for a trade.
Signing Nilsson is pretty much Condon 2.0; although he might be better he's still an older asset.
I don't think it's fair to say that Nilsson has been better than Anderson. He was better during his first half here, but he's significantly slowed down the last dozen or so games.
I don't even think term or AAV is a major issue at this point when it comes to Nilsson because there's so little money (relatively speaking) on the books the next 2-3 years, another Condon/Hammond type contract isn't going to have many consequences. I think the issue isn't what is the appropriate AAV/term to give Nilsson, I think the issue is who are the right two goalies to keep out of Anderson/Nilsson/Hogberg?
I have no issue with the Senators giving Nilsson term, especially if they decide he has more upside than Hogberg. I haven't seen Hogberg in the AHL. I don't know who is better. Nilsson's bad numbers might be a good thing for Ottawa, because if they decide to go with Nilsson, it should lower the amount of competition they'll face from other teams to lock him down. When Condon was a UFA, there was a lot of interest.
It's all small sample sizes, so it's all very reactive, but I think where as when Nilsson first came here a lot of people were looking at it like Nilsson vs Anderson, I think it's shifted more to being Nilsson vs Hogberg. If the motive of the team is not to tank and not to try and become the Oilers 2.0, then I can see them going with Anderson and their choice of Nilsson or Hogberg (if Nilsson stays) and then possibly flipping Anderson closer to the deadline if the team is out of a playoff spot. (While anything can happen, and I would love for this team to win, I assume it is a yes that they'll be out)
