I think Nashville GM would have to be more than drunk to do that deal....

neither team likes that deal.

NAS immediately improves their C depth and PP at the same time. They lose JOSI but they can actually afford to move on from him with Subban, Ellis, Ekholm and eventually...Fabbro.

Krejci scored 73 pts with a 2nd year LW and an assortment of AHL RW. He would immediately become NAS highest scoring player.
Torey Krug is the 5th most productive offensive defenseman in the NHL and was outstanding in the playoffs this year
Danton Heinen is a versatalie, young, cost controlled two-forward. He can play LW, RW and even C.

this would never happen
