Seahawks' receivers had hand in success

With his NFC championship victory, Seattle's Matt Hasselbeck has finally been afforded a level of recognition he had been lacking. Almost everyone agrees that Hasselback is a far more complete quarterback than in years past. His statistics back this up, as Hasselbeck had career highs this season in both yards per attempt and in passer rating.

What is Hasselbeck doing this year that he wasn't doing in previous years, and how much better is he from a metric standpoint? The analysis I performed shows Hasselbeck has made a number of improvements in his overall consistency, but it might be as much due to the improved performance of his wide receivers as it is Hasselbeck.
