One of the goalies in Col must be available for the right price.
Tough to say what's going on in Sakic's mind. He seems to have accepted this as another sort of 'development year' (in that he didn't do anything to address secondary scoring all off-season, he seems happy to wait until the 2019 off-season at least with his two 1st round picks + Makar joining the fold), so from that perspective Varly should definetely be available. He certainly made moves to replace him this off-season by bringing in Grubauer + Francouz. But then the Avs are winning right now, Varly is playing lights out hockey, and he's one of the longest tenured players on the roster and perhaps an important part of the room. So does he really want to break that up?
Unless Sakic's planning to make a big move to address secondary scoring and wants to seriously compete this year I hope he moves Varly sooner rather than later (since he's healthy, playing really well, and teams badly need keepers), but I also just see Sakic as the sort of GM who might pass on assets for Varly in favour of letting him walk in the off-season, just so that he doesn't shake up a team playing pretty well.
