I live in san diego and watch more chargers games than bills games. get your facts straight. vincent jackson played all 16 games last year. it was 2010 where he held out for nearly the entire season (actually one of rivers' best seasons, so there goes the absence of vjax argument). you also left out rivers' 6 lost fumbles - and he literally fumbled away the chiefs game last year.
Rivers was great, statistically speaking, from '08 - '10, but he's been totally mediocre since then. And he's been at his worst in the clutch and in big mathups (tonight, 2nd half last week, last year vs Pats, Jets, etc.). The guy is slipping fast and it appears his best days are behind him. He's quickly approaching Carson Palmer territory.
