Well by design the prevent defense is a passive defense or a not aggressive defense. So passive ant prevent are pretty interchangeable and aggressive is the opposite of passive.So let's see, first 'oh please'. No where did I comment on the level of "aggressiveness" of the teams listed. Second, the point I made, clearly so, was the defenses listed do in fact play prevent. You suggesting they don't is verifiably incorrect.
Lastly, as far as how aggressive their defenses are compared to the Patriots? That is your decision to be mad and/or sad at the lack of the Patriot's aggression comparable to others. My preference is a 3 phase complimentary football team that optimizes the chance of SB victory (personnel will dictate how BB & staff work out that complimentary equation). Whatever D can be or needs to be played to achieve that I am good with. If you are not? That's your own judgment call...
Early in the fourth quarter the pats were only up by 9 and seemed to go into a prevent or not aggressive defense. TB eventually scored. On TBs last drive with only about a minute to go the Pats were giving up 20+ yards a play. So no, I don't think the Broncos or Seahawks go into a prevent with only a 9 point lead in the 4th quarter or play so passively that 20+ plays are gimmes at the end of the game.
