Getting a guy like Marleau could have benefits in the team's development, however:
1.) While the Sharks might like to have Miller, I have my doubts that they would like him at $6 million as this seems a bit high for a back up goalie. Further, the Sharks are only gaining around $600,000+ if the two contracts were traded. While this is nothing to sneeze at, it's still not a big load off of their cap. Also, why wouldn't they look for a cheaper option in trade, or in a UFA for a back-up?
2.) What do the Sharks do to replace Marleau's scoring? That's 25 goals out of their line-up.
3.) The Sharks might be without a 2nd for the next two years, but this trade puts the Canucks without a 2nd. for possibly two years. This is a killer for me.
4.) There's a lot of hope in that the two players *could* re-sign with their new teams. I'd expect that it's just as likely that Marleau and Miller would both be more likely to sign with SJ (assuming a contract was offered).
5.) I'd be happier giving the ice time to a younger forward.
6.) Depending on how the season was going, if SJ were interested in Miller, then I'd be inclined to trade him there (with his consent) for picks and/or prospects at the trade deadline. As they are without any 2nds for the next while, and they are unlikely to want to trade a 1st straight up for Miller, then I'd go with a 3rd and a very good prospect, or, a 1st for Miller and a 2nd Option #2 is likely more acceptable to them as it could just be like trading down several spots (assuming the Canucks do poorly this upcoming season).
