He is good at all those things and I never claimed he isn't. He is obviously a good and useful player but what I said about him is true, he has holes in his game and the skepticism about his overall play isn't unfounded. Tunnel vision, defensive question marks, and looking like he's playing on an island by himself namely being the criticism. If it wasn't, he wouldn't be on the market at all. The question isn't whether Necas is a good or bad player, it's more is he good enough to pay him $7M or more that he's rumored to be asking on a long term deal because at that rate you make him one of your key cogs. Him being on the market indicates that the Canes do not see him as a key piece.
There is a possibility that it's completely a system mismatch and that Necas would thrive away from Rod's system, but that's a huge gamble. People also love to sing Rod's praises around these parts, so if a player is at odds with one of the NHL's supposed best coaches does that say more about the player or the coach?
He's a useful player but I wouldn't make him a key part of my team if I want to win the cup, and that's what the team trading for him will have to do considering his salary asks.
