I think Buffalo would certainly be losing in a one for one Risto for Henrique deal, but maybe with significant adds from Anaheim's side it would be possible. Henrique will be turning 30 next February, just came off a pretty bad season, and has a pretty rough (5,825,000 AAV) cap hit. Obviously Rakell is the big fish from Anaheim, but another interesting player would be Daniel Sprong. He's a pure goal scorer with a lethal shot, though Anaheim might not be willing to part with him, as they are rebuilding and he may be considered part of their young core.
