Weddle should be fine. He's one of the more talented safeties in the NFL and the Chargers use him in a way that is beneficial to his overall fantasy production. The main problem last night was the Chiefs inability to move the football on offense. They really didn't have any long, sustained drives and consequently Weddle didn't have a lot of tackle opportunities. Even though Weddle may not turn out to be the superstar fantasy option he was in 2008, he's still should be a very serviceable fantasy DB. Weddle has too much talent and previous fantasy success to drop this early in the season. Give him another week or so and if he still is disappointing, drop him at that point.
