The Seahawks have a great defense, yes. But with a shaky offensive line and one of the worst receiving corps, you don't make it to the Super Bowl two years in a row. Russell Wilson made that happen. His play action ability is what made the Seahawks a Super Bowl contender. Since Russell Wilson is a starter, the Seahawks had a top-ten passing offense in each of the three years. With another QB, they probably wouldn't have made it to any Super Bowl. The shaky o-line lost Carpenter and Pro Bowler Unger. Who would want to play behind that line in 2015?
He should not be the highest-paid player like he wants to be, but he definitely earns a restructured contract.
