TT's offense does look pretty formidable. I've watched them for several weeks and they seem to score at will. I agree that they aren't facing defenses as good as ours, but I think dismissing their offense as "smoke and mirrors" is kind of like whistling past the graveyard. Their success comes from almost perfect execution. Their QB is very, very good and rarely makes a bad throw. And his receivers are physical and very athletic.
But, that is not to say they can't be stopped. The key is to disrupt their timing. If you can jam their receivers at the LOS and get pressure on their QB, then they won't be nearly as effective. Also, after McClain and Hightower slam their WRs a few times then you might see some drops and guys changing their routes to avoid the hits. All of that disrupts their passing game. I also haven't seen any teams running blitzes and changing things up as much as our defense.
Bottom line -- I think TT is very good and will be hard to stop. But I also think we have the personnel to match up pretty well. And CNS will put together a plan that will throw more at them than any team they've faced this year. It should be a very interesting match-up.
