Maybe Hilll is buying in. Maybe he is not drinking and has gotten serious about his game and Reggie Scott's plans to stay healthy and focused. There seems to be a ton of buy in on this team.
Here is another thought. Maybe it is game planning. Between Wade and McVay they should be able to analyze opponents well. The Seahawk receivers are not a dominant unit until the play breaks down and Wilson scrambles or runs, then dbs drop coverage to get in position to stop him if he gets to them. The second they do that the receiver gets open and Wilson throws the ball. Maybe they said don't pay any attention to his scrambling unless he crosses the line of scrimmage. Don't drop coverage at all. Wade talks about discipline with his defense. This type of coverage discipline would and I think did work against Seattle. I think Jacksonville did the same thing. Wilson is not Kaepernick. He doesn't burn defenses with long speed.
Give him the short gains and take away the big play and his amazing trickery is foiled.
