ENGLEWOOD, Colo. (AP) — With impeccable timing, the Denver Broncos christened their sparkling new indoor practice facility Wednesday with the temperature minus-2.

This was also good preparation for the Broncos’ visit to the climate-controlled Edward Jones Dome on Sunday in St. Louis.

Yet, while they may have gotten out of the cold blast that’s freezing the Rocky Mountains, they can’t escape this uncomfortable truth: it’s November and their offensive line is still a mess.

After changing three-fifths of their O-line last week, the Broncos brought in Richie Incognito for a workout this week. Although they didn’t sign him, they left open that possibility.

Their front line has been unable to get the ground game going and has allowed a trio of sacks on three-man rushes.
