1. No, Greg Williams has been around a long time, OCs adjusting to him and he adjusting to their adjustments. And he's just the opposite of stubborn, really he's quite creative.
2. Are the offensive lines more physically imposing? I don't think so. If they've committed to any one thing on defense it's the lighter, faster linebackers, one of whom I guess is adjusting to his first season starting as an OLB, and the other starting his first season as a MLB. So when you see one of those guys blocked by a tight end or worse, it's on our secondary to make that tackle now. Hello extra yards.
3. No, well I'm not so sure how many times I'd have Brockers drop into coverage
But if anything I think they're bleeding worse than ever without his creativity.
4. Same response as 3. I love the creativity.
5. Yes, this is it. They were paper thin to begin with, and the injuries to the line, plus the franchise cornerback? Of course they're hurting.
6. No, I don't really believe in slumps. Rather, I think different teams have different strengths and weaknesses, and that's just the regular ups and downs of football.
Cool list of questions though. I think you should have made that a poll as I'd be interested in seeing what everyone thinks on the surface if they were forced to choose one reason.
