keep in mind the context of my reply though. The statement was that Lu could put you in the "cup hunt" and that's why I said if it was true, why would you be trading him (playing devils advocate to it.) I won't deny that Lu could make a team better or help get them into the playoffs... but some of the people here are saying how great he is (saying how he'll still be a top goalie when he's 40) when in reality he's at the age when goalies start to "slide" away from their prime years.
So look at it from Florida's view... they have a roster full of prospects right now that haven't proven much. Why would they trade some of those away, for a goalie that'll help them "win now" when they really need a goalie that'll help them "win tomorrow" (so Cory would probably be the better fit) when those prospects should be hitting their prime years (and by that time Lu's probably already retired)
The Panthers have Markstrom and maybe they think Lu is a big part of Schneiders success, so signing Lu to mentor Markstrom may well be worth it to get Markstrom to where Cory is now.
