The time to have considered trading Varly is likely gone. I am not even sure a 2023 1st round pick from VKG would entice Lou enough to pull the trigger.
No, this should have been a consideration a month ago when the market was hot and heavy on netminders, Lou would have gotten a good deal as well as cap space and there were a few backups still available. Now, most teams are cap-strapped and set at the position and there is absolutely nothing on the FA market....
As enticing as this option is, I don't see it happening
