I don't see why San Jose would trade Pavelski for Nash.
As I said when I brought this up this morning:
SJ is desperate.
Thornton and Nash are BFF.
Nash's ceiling is undoubtedly higher than Pavelski's; look what Pavelski did on Thornton's wing. Pavelski is a very nice player, but Nash could be devastating on next to Thornton.
Pavelski does not have NTC protection on his contract, and at a $6 million hit, it is not too far of a bridge to gap. Also believe it or not Nash's contract runs out before Pavelski's.
I said Pavelski and Havlat for Nash and Hagelin, because SJ has been interested in Hagelin before, so he is a carrot to pick up in lieu of Nash's contract. Havlat is a nice asset as an expiring contract, and if he is healthy he can certainly help the 2nd line. If not, Miller and Fast are in the bullpen. Plus as an expiring contract it is not a big commitment and he will have resale value.
If I have read correctly, SJ is interested in Staal for Pavelski. That would be a tough pill to swallow but you probably have to do it. With that being said, SJ has to take Nash in any deal in my opinion. Nash waives his NMC for SJ, and SJ probably would have genuine interest in him. If you want to go with Nash and Staal for Pavelski and Burns, it is terrifying even in terms of value and cap hit:
NY - $11.775 Nash (7.8) and Staal (3.975)
SJ - $11.760 Pavelski (6) and Burns (5.76)
The Rangers could use Burns at defense in this scenario even, although I certainly wouldn't mind him at forward. However with Burns' versatility, they would have options in terms of which hole they would want to replace. This also allows the Rangers to move Hagelin for a net presence. As I have said all season, Hagelin is a movable asset, as Kreider really makes him redundant.
Just some more food for thought.
