As they did a month ago in San Diego, the Broncos huddled near where the Chargers were warming up. Some Denver players were facing the Chargers and pointing. It appeared as though no San Diego player even noticed the Broncos’ bait job. The Chargers were far more interested in stretching their muscles than their tongues. On Oct.19, the Chargers were incensed when Denver pulled the same trick on their home field. A shoving match ensued before the Broncos went on to beat the Chargers and take a commanding 3.5-game lead over San Diego in the AFC West. A lot has changed since then.The Broncos had nothing Sunday -- not even effective pregame bravado.
