Super Bowl XLVIII.
Seahawks inactives: WR Bryan Walters, RB Christine Michael, OT Michael Bowie, OG Caylin Hauptmann, TE Kellen Davis, DE Benson Mayowa and DT Jordan Hill. With Michael Bowie inactive, that means you're likely to see the James Carpenter & Paul McQuistan rotation at left guard continue, and with Kellen Davis inactive, you'll likely see more 6OL Jumbo package looks with Alvin Bailey.
Also, deactivating the third TE means it's likely you'll see Seattle run more 3WR and 4WR sets, with Percy Harvin a big part of the gameplan.
Broncos inactives: CB Quinton Jammer, QB Zac Dysert, RB Ronnie Hillman, OT Vinston Painter, OG Chris Kuper, TE Joel Dreessen and DT Sione Fua.
