If you find yourself in a Christmas chariot this week, perhaps a pair of Broncos will be carrying it. Denver inside linebacker Alex Singleton and kicker Wil Lutz looked like pros over the weekend at the Colorado Ballet’s performance of “The Nutcracker.” The duo made brief appearances in the ballet’s rendition of the Christmas classic on Sunday night at the Ellie Caulkins Opera House downtown. They carried out a chariot with a ballet dancer inside at the start of the Arabian Dance.
