Hard to judge the Pats' O-line overall based on last night. The Raiders have a PATHETIC pass rush (their leading sacker last year had 4 whole sacks, and they added no one), and they were using a 3-man line most of the night with little blitzing.
But that being said, the Pats didn't move the ball up and down on the Raiders, which makes me think they're not as good offensively. Good. I think they'll have trouble with teams with good defenses, especially away from the confines of The Pad (formerly the Razor, now that P&G bought out Gillette).
