I feel the need to interject here, because some of the things people are saying in this thread are discrediting him the wrong way. As someone who has watched him almost his entire career in the NHL, I'll tell you exactly what the issue with Wolski is.
He can't create chances for himself. He's an average skater, and this doesn't just mean he isn't fast. He's not very good at staying on his skates when he's being pressured. He's easily knocked off the puck, easily stripped of the puck, and just generally bad at moving around other players. The reason for his success in Colorado should be... fairly obvious.
06-07, he emerges in the league with a 50 point season. A flashy forward who can find the net, and his teammates.
07-08, he slumps a little bit -- only by 2 points. Less goals this time.
08-09, he continues to slump down to 42 points now, and 4 less goals for only 14.
Now, let's follow the last few years in the career of the man who made Wolski look like more than he is -- Joe Sakic
06-07, Sakic has a typical year. 100 points in 82 games.
07-08, Sakic starts to succumb to injuries. He only plays 44 games, but still puts up 40 points.
08-09, Sakic's last year, only 15 games played.
The 09-10 year, Wolski bounces back -- but look at the Colorado team as a whole. That year was the ****ing miracle year for that team that was failing to reach the playoffs year after year. Stastny mustered up 79 points in 81 games -- when has he gotten close to that since then? Stewart had 64 points only to be traded for being a lackluster player who can't score the next year. Maybe you guys even remember Brandon Yip, who had 19 points in 32 games his rookie year in Colorado, and hasn't sniffed that point progression since then.
That season was a crazy anomaly. Everybody on that roster overperformed, including their goalie, Craig Anderson. The point is, Wolski is useless without players around him making the plays. He can't create offense for himself, and he's not going to be a difference maker on any team. He's the kind of player you pick up when you need a spare part to feed off the top tier playmakers you already have. The Rangers had no player like that to speak of while Wolski was here.
