Very misleading stats. Look at Vermette's numbers in the surrounding seasons from that 2010 season, and you'll see why he's not in Nash's league. Same with Huselius. You can't just pick one season (from 3 years ago) and use that as proof that those players are as good as Nash.
I'd explain it the same way I'd explain Filppula having similar numbers as Zetterberg last year. Doesn't mean he's a better player.
I'm not saying these players are better than Nash. I'm saying Nash is an underachiever so far in his career. He is paid to be the franchise player, and make people around him better. If he was paid 5 million, it would be different, but he's not.
