I really like Nash and I wouldn't take back that trade at all. It's still smart of us to consolidate our 2nd/3rd line grinders in Anisimov and Dubinksi into a first line, 30-35 goal scoring player, even if Nash is not the 40+ goal scorer we thought he'd be (though technically he was on pace for that last year, or damn close to it).
But Nash is a bit of a drifter and doesn't seem to be a #1 offensive catalyst. He puts the puck in the net, but he disappears for other times instead of getting consistent pressure.
IMO he's an elite second scorer. Still need a true #1 offensive player here, but Nash is a great #2, one of the best in the league. Of course... when we traded for him, we thought we had Marian Gaborik as well, and him and Nash could have been what we needed.
