The Seahawks offense is centered around Marshawn Lynch. The offensive coordinator runs the offense through Marshawn Lynch. Russell Wilson is a game manager. The Seahawks OC is creative.
The Seahawks also have the top defense in the NFL with a very strong secondary that keeps them in games and wins games for them.
The Panthers offense is centered around Cam Newton. The offensive coordinator runs the offense through the #4 and #5 offensive options and then Cam Newton. Cam Newton is a game changer. The Panthers OC is predictable and unimaginative.
The Panthers also have had nothing to write home about with their secondary over Cam Newton's career, and Cam Newton has had to play to win in spite of his OC, defense, and lack of offensive weapons.
You could insert any fairly intelligent mobile QB into the Seahawks offense and they would be doing as well or better than Wilson.
Take away Marshawn Lynch, insert DeAngelo Williams, and then replace the entire Seahawks secondary with whoever is in free agency come August. Toss in an old used up offensive mind for the Seahawks OC, and then show me Wilson can carry a team.
