I watched a ton of Broncos games when they were always heavily at home from 1996-2005. Every time the line is expecting a blowout, the Broncos either lose are barely wins those game. If Phillip Rivers doesn't do his usual bone head picks, the Chargers should be able to hang in this game. Division Rival games are always tough, quick example would be the recent Saints/Falcons, 49ers/Rams, Pats/Bills game.
I have a problem with the Chargers. Don't know if I feel they 'owe me' or what,but lost more money on them then any other team in past 3 years. I always think I have them in a good spot play. And I always take it in the ass.
