Anaheim won't trade anyone if they're still where they are now in the standings (2nd in the west) at the deadline.
I like Iginla but there's a lot of mileage on those legs and Calgary will want a top prospect for him in return. Just depends on how close a team thinks they are to winning the Cup.
On a side note, the Toronto media will work everyone into a frenzy with unfounded trade scenarios for all three of those guys ending up there. They won't which then seamlessly transition into who will sign this summer (Getzlaf) as a free agent.
