Normally, the Titans generate pressure from just their front four, especially Jurrell Casey and Derrick Morgan. However, against the Raiders, there was almost none.
Matt McGloin wasn't sacked or even hit by the Titans, and though he was hurried occasionally, it wasn't very often.
This is even more unusual when you realize that the Raiders don't exactly have a top-five offensive line. So what was the problem?
I noticed that there were very few linebacker, corner or safety blitzes called in that game. Whether Jerry Gray and Gregg Williams thought they were unnecessary against McGloin or that they assumed the front four would generate enough pressure, I don't know, but it didn't happen.
It looks like that, even with a great front four like the Titans have, they'll need to dial up the occasional blitz to keep opposing quarterbacks under pressure.
