I think they did play very vanilla. We didn't see a lot of extra wrinkles, other than an onsides kick, which probably won't happen in the playoffs unless we need it. Certainly not as a trick play. Explosive isn't the same as not playing conservatively. Big, explosive gains can (and did) happen, regardless of how basic the formations are or how many little wrinkles are added to the play. We also weren't playing from behind, needing a win to secure anything for the playoffs, so there was no need to take huge gambles.
World Champion Seattle Seahawks football. It's an addiction, and there is no cure.
