IMO Turris is one of the more underrated players in the league, he literally did it all for Ottawa, PK, PP, good face-off guy and could put up points. Duchene is not going to do some of the things Turris has done so well for Ottawa recently but will provide some more offense for them (though Duchene and Turris have had similar offensive outputs in recent seasons.) But Duchene is 2 years younger and fits a little bit better into there age core, I think its a win-win-win for all teams. Nashville now had a deadly 1-2 punch down the middle that could be one of the best in the league.
