I'd personally we use it this year and it would be ideal to have a guy who is here for a bit. Windows are way too short to waste years and the Avs are on their way to that... but they have the ability to change that. This team isn't that far off. 2C, good middle 6 5v5 goal guy, and maybe a depth defensemen. Maybe you have to sacrifice the middle 6 guy (or better yet Landy and Nuke come back and don't skip a beat to eliminate it), and don't go nuts on the defensemen.. but Avs have the assets to do that.
I'm having a hard time seeing a clear set of possibilities especially with the extra cost involved in just moving salary around to fit someone mid season.
I see a lot more options for long term solutions in the off season if we have the pick.
