Why would they trade him in the division?
Well its Nash's call or its a no go. If wants to play for Detroit, Columbus sucks it up and trades him for a return or they keep him. Division trades do happen, maybe not as much as outside of the division but its possible. Its even more likely when a player has a NTC.
Do I think the Wings will actually get Rick Nash? Eh not really; probably slim to none. But hey I would love the guy to be a Red Wing. Did I think we had a shot at Hossa? Hell no! Hasek? Hell no! Those both happend. Look at what we traded for Hasek too... (yeah he was getting somewhat older but still). s***, even look at the Tigers signing Prince Fielder... Detroit was NEVER mentioned and wasn't considered an option and then BAM, they signed him. Yes we are talking about a trade here but my point is it is a possibility, just an unlikely one.
As far as who I would give up...? Hard choice. Wings draft scouts seem to always pick "diamonds in the rough" (solid late round picks) so I wouldn't be mad if they traded a 1st/2nd rounder or two. I'd try to sell them on picks and some of our replaceable prospects. I wouldn't mind trading Emmerton, Mursak, etc. No way I'd trade Jurco, Smith, Nyquist. I'd consider trading Tatar as well. Maybe sell them on that their goaltending is awful and add McColloum? Roster players I'd consider moving are ALMOST any of the bottom six. As good as Filppula is doing, trade him while hes "on the up". NASH >>>> FILPPULA! I'd want to hang on to Franzen, but I would exchange him in Flippula's spot. Erricsson can go as well if they want him. I would like to think some kind of package of the names and picks I stated would work... Again though in all reality I give Detroit a 0-12% chance of landing Nash.
