‘The Bills will need every tool in their box and a few new ones to beat San Diego, which presents matchup problems up and down the board. Putting pressure on QB Philip Rivers, who leads the NFL’s highest-scoring team, is the top priority, followed by limiting the all-purpose yardage of RB LaDainian Tomlinson. With DE Aaron Schobel (ankle) hobbled, Buffalo’s defense, which has produced just 10 sacks, will need to blitz more and take chances against Rivers. New England never touched him last week and paid the price with three TDs. His fleet of 6-5 receivers tower over Buffalo’s secondary, that is expected to be without CB Terrence McGee (knee) again. Offensively, Buffalo’s line needs a big game. QB Trent Edwards is coming off a concussion and can ill afford taking any more big hits. The Chargers have 14 sacks in their last four games. The Chargers may even have the edge in special teams in this one, with a healthy Darren Sproles among the NFL’s best returning punts (14.3) and kicks (30.4). San Diego is 9-5-1 as the road team in the series, winning at Buffalo 24-21 in 2006.’
