He may not be looking for a major guarantee. The Avs don't like giving out any guarantees. He could be looking for just 5 games like Jost got to get his $25k bonus. He could be looking for a 10 or 10+ games played bonus. He could be looking for 11 games, just to keep his contract from sliding.
Whatever he's looking for, there are many teams out there more comfortable giving out guarantees than the Avs. The question is how much will both sides bend in what they're comfortable with.
Unfortunately, Butcher has never given me the impression he wants to bend much. Now that he got the Hobey Baker, he probably thinks he doesn't need to. Lindholm and Mironov probably make the Avs think they don't need to either.
