Hey my fellow fantasy heads, I need some help here. Should I start Ben or Sanchez this week (four)? Here is what goes thru my mind:

New Orleans seems to have a terrible pass defense so far this year
Chargers have a good pass defense
Sanchez is just a rookie, but playing well, will N.O. force interceptions on the blitz D?
Chargers seem to have great corners, and some injuries up front on D
I am starting S Holmes at WR

Can anyone out there help me put things into perspective and make a well informed choice this week? Any feedback will be of great help!
