Peyton Manning drew his biggest ovation on an incompletion. Blasted by defensive end Bruce Irvin, the four-time MVP who missed all of last season with a neck injury that required four operations bounced right back up, shook it off and threw a 22-yard bullet to Brandon Stokley on the next play. It was the highlight of a mostly forgettable home debut for Manning, whose Broncos lost 30-10 to the Seattle Seahawks on Saturday night after Denver's backups were outscored 21-0.
