Yeah this is the issue with Ullmark and Saros. They are both gonna want long term deals and the Wings have already invested a 1st and 2nd into goaltending (and both prospects are doing well). At best we are probably looking at a Markstrom esque return in 3-4 seasons if Cossa looks ready to take over. At worst we'd end up with an anchor contract.
Gibson probably fits our timeline the best, but obviously has not been great with a really poor Anh team. I do have more faith him bouncing back with a better team just do to him being 30 vs Markstrom's 34. His 3 more years would probably be a perfect transition to Cossa with Cossa backing up next year and then taking over in the 3rd season.
If we are giving up assets to get a meh non long term goalies then Stevie has to be all in about moving contracts and fixing this team both for now and in the future. You have to bring in at least a top 4 dman and a top 6 forward. Get creative in moving out Holl, Maata, Husso, Fabbri etc to create the cap space needed. Maybe even figure out a way to deal a guy like Copp. If you spend assets on short term players then it has to be playoffs or bust next season.
