It's definitely time to move on--Elliott is terrible. Everyone got all jazzed up because he had one good season in a perfect storm of a situation--great team, great coaching, and he stepped in and played well at the right time and was able to ride the wave. The Elliott you're seeing this year is the real Brian Elliott. He has below average starter's potential, and that's about it.
As far as his keeper value, I'd say it's pretty low unless he somehow lands a Mike Smith-type offseason signing that sees him going to the Predators...and even then he's not as talented as Mike Smith so it's not even a fair comparison. Can Elliott play well in spurts? Sure. But so can every other backup goalie in the NHL. If this is a full keeper, I'd sell him as quickly as possible and try to get some value from him while he still has any at all; if this is a partial keeper, you should've dropped him a looooong time ago.
Maybe you can target someone like Khudobin in a trade? Or drop Elliott and pick up Desjardins if you need immediate help?
