I still think Varlamov for Bobrovsky makes some sense.
Just for context, Bob this season has still been worse than Varly up to this point, and that's including Varly's recent stretch from hell.
Bob is also one of the worst playoff goalies in the league and will SURELY be asking for one of the worst contracts in UFA. Which the Avs should avoid at all costs, he's and extreme high risk asset
I really don't see what the upside is for trading for him.
At least with Varly there is a chance the Avs decide to resign him for a cheap 2 year deal if he bounces back, but even if he leaves it doesn't change much.
IF you are going to move Varly at least get something useful in return and if you want to make damage in the playoffs I'd STILL go with Varly even after this nightmare stretch of a small sample size.
