Monday's Matchup: Broncos (2-3) at Chargers (3-2) 8:30 p.m. Eastern, ESPN Peyton Manning looked like a has-been the last time he played a Monday night game, throwing three interceptions in the first quarter and losing badly to Atlanta in his second start with Denver after returning from neck surgery. He has since thrown for more than 300 yards in three consecutive games, with eight touchdown passes and no interceptions, proving that he may be a different player than he was when he played for the Colts, but that he is still a force. The Chargers, however, can control this game if Ryan Mathews can take the solid work he has been doing in 10 to 14 carries a game, and apply it to a 20-plus-carry effort. The Broncos have the makings of a good team, but if Manning is not on the field, he cannot engineer long scoring drives.
