Without Lynch, imo, the offense is unpredictable.
Unpredictable Darrell Bell is one of the most dangerous OCs in the game.
I actually expect an improved offense, one that is able to morph in and out different sets and schemes with more ease than years prior. One that isnt built upon the notion of being bigger, stronger, More physical than the opposition but one that can explore a variety of strategies that will leave opposing defenses and their coordinators confused on how to gameplan, mismatch, cheat pre-snap, all in all how to attack the Seahawks offense.
With Lynch it was predictable, more often than not you could sell out, and battle physicality with physicality. With this approach you really could just game plan punching Seattle's run game in the throat and pressuring Wilson. Which meant teams just stacked the box and that forced a lot of error and poor execution.
Without Lynch, and know with an RBBC approach of physical, versatile RBs and Wilson's ability to spread the ball as well be a dual threat teams are going to have a much harder time trying to key in on one or two aspects that can throw the offense off balance because the Seahawks have multiple weapons and now they are in a position where they don't have to force feed the Ball to anyone. Not like they did with Lynch and Harvin. And that's why unpredictability is scary and dangerous, you can't just focus to stop any one player, you have to focus on all of them and hope you execute and matchup better at all positions because that ball will be touched by every active player.
And Wilson proved last season that he has the talent to be dangerous getting that ball around efficiently.
