The gadget plays were put in place for a reason. For all the special things he's able to do, Russell has thus far been fairly inept in empty formations, can't throw short middle or step up in a collapsing pocket. So, what do teams do? Load the box, blitz the run gaps, play press man on the outside. If you got halfway decent corners and can spy Wilson effectively, then it's a wrap for our offense so far. The Seahawks paid a king's ransom for Harvin and designed a playbook for him to address this exact issue. They saw this before any of you did. Not being able to get anything in the short middle is a huge handicap to the OC and our receivers. It dials up the degree of difficulty on every single play up to 11. Basically conceding downs on empty sets is unsustainable, and you can't scrap those from the playbook because no one's biting on play-action on 3rd and 5+. One work-around is to feature these gadget plays to compensate for our inability to get anything in the short middle.
If you take out the gadget plays and run play-action exclusively, then you got the exact same thing we saw at the end of last year. Teams copying the Arizona/St. Louis formula and our offense struggling to establish a quick-strike offense due to the QB's inability to hit short middle in an empty set on third down.
Based on how teams are now defending the Seahawks, please someone tell me how removing the gadget plays address anything? How does smashing Lynch into a 8-or-9 man box address anything? The solution, IMO, is to execute down the field. Be willing to throw quickly and be able to make the plays. That's an execution issue, not a design issue, and that's what will open everything else up.
