DENVER (AP) — Joe Flacco looms larger than life in Denver, and not just because he engineered the stunning upset of the Broncos in the playoffs that propelled the Baltimore Ravens to the Super Bowl title.

The league’s marketing campaign for next week’s kickoff game features several large banners of Flacco fluttering from lamp posts on downtown streets — and a giant one several stories high that hangs at Sports Authority Field alongside a banner of Broncos quarterback Peyton Manning.

That has drawn an angry public reaction from Broncos fans who have taken to Twitter and to the streets to vent their frustration. One local sportscaster used a Sharpie to draw a mustache on a Flacco poster hanging along Denver’s 16th Street Mall, and covered another with tape.
