re: Hey blues remember that Shaun Phillips guy?

Not entirely his fault(not saying he's good against the run either). I wouldn't say the Chargers had a good Dline. You put a player in a bad position and 9 times out of 10 he will look bad. Just think Harper in coverage for most of last season.

Edit:
And that's the main reason I don't take PFF rankings at face value. They are a good indicator(especially on offense where each player can stand out good or bad individually), but defense is where it truly takes 11 guys being on the same page and if one guys isn't doing his job to other guys aren't going to look good either most of the time.

Someone doesn't take up the double team, the CB misses the jam, the LB takes the wrong gap, etc. The other guys will have to try to correct that mistake and then their responsibility suffers.
