While seeing Chara go would be bittersweet, I would have no remorse for kicking Lucic to the curb. In my opinion, Lucic is completely overpaid and overvalued. It is actually painful for me to watch him play. Personally, I think Brad Marchand is a much better player who doesn't get nearly half the credit he deserves. Last year when Marchand was on his scoring drought he was hitting posts several times a game, meanwhile Lucic was having the puck bounce off and over his stick. About the only reason I'd be okay with the Bruins keeping Lucic around another year is because he'll probably play great next year because it's a contract year. Of course, that could completely backfire if the Bruins get sucked into the hype and then sign another guy who doesn't score to an albatross contract.
Here are a few links to some of my previous posts so you don't think I'm jumping on the trade Chara and Lucic bandwagon. If past comments on ESPN message boards were searchable, I would have a ton more.
