Quite frankly a good, old UFA goalie is the last thing Detroit needs. A young goalie that won't get protected in the expansion draft, like Georgiev, makes a lot of sense. But taking on an older goalie when the team won't be playing meaningful hockey for a few years, stealing games and artificially improving Detroit's finish for a few years, only to see them decline and be a contract anchor right when the team is ready to compete would be the worst case possible IMO.
Now, if you want to attach a significant asset along with a bad contract or two, and throw in Markstrom's UFA rights, then that might make sense.
