Put me in the camp that wants to wait and see how Bura does the rest of the season and the playoffs before committing to him. He has proven this year and in the past that he's a very streaky player, and guys like that are very risky to sign long-term. That's because streaky players can sometimes have entire seasons where they play poorly.
That being said, before this season one of the Avs biggest needs was a winger who can shoot the puck. Since we don't seem to have a lot of that in the pipeline, and Bura is still young, I think he's our best bet at filling that need for the next several seasons.
All that being said, signing Nuke would be my priority.
