ENGLEWOOD, Colo. (AP) — The Denver Broncos look like they’re ready to start the season.

They had an impressive preseason debut against the Seattle Seahawks, the team that throttled them in the Super Bowl, and they christened San Francisco’s new stadium with a 34-0 shutout of the 49ers Sunday.

Denver’s starting offense is in midseason form with three scores in four possessions with Peyton Manning completing 22 of 27 passes for 182 yards and a touchdown.

And they haven’t even shown the offense they’ll unveil against Indianapolis on Sept. 7, when starting running back Montee Ball returns from an appendectomy that’s sidelining him the entire preseason.

Denver’s front-line defense has been just as impressive, allowing one TD on four drives.
