‘The road ahead isn’t easy, but there are winnable games. The Bills travel to Los Angeles Sunday to play the Chargers. The Chargers are 3-6 and 1-3 at home. Philip Rivers, the team’s longtime quarterback, is in the concussion protocol and may not play. With or without Rivers, the Chargers have plenty of weaknesses. The Bills can win this game and improve to 6-4. That would be a big boost before an even harder stretch ahead.’
