Denver's offense wasn't just great, it was all-time great. They were top 3 all time in 3 category's, PPG, First downs per game, and YPG. Tied for first in 50 point games and since 1990 in total points scored, the 2013 Denver Broncos were/are #1 in the league. and had they won that SB, they would have been agreed upon by many as the greatest offense ever. That takes a whole lot of game-planning and scheming to stop. Also, that same season the Patriots beat the Seahawks, Denver nearly did as well at Century link with them not even being able to get the ball back in OT.
I don't think this Patriots defense is as good as some make it to be. Don't get me wrong, it's a good defense but I wouldn't put it in the elite category. I think they're very dependent on scheme and game-planning given the lack of All-Pro(Even Pro Bowl) talent on that defense. Also, when addressing their #1 opponents PPG, I honestly have to say that their stat is pretty inflated given the severe lack of elite or upper echelon of NFL offenses they played. I would not put Buffalo, New York Jets, or Miami near that category. They played 6 of the bottom ten teams in the lowest PPG category which consists of LA Rams, Cleveland Browns, NY Jets, Houston Texans, Cincinnati Bengals and San Francisco 49ers. Denver and Baltimore themselves weren't exactly great scoring offenses coming in at 20 and 21st respectively. The only team they played within the top ten in scoring PPG was Arizona and we know how their season went down. I can't give them credit for limiting Pitt to 17 without Big Ben in the game honestly. To their credit Buffalo is 10th in scoring PPG, but that's a very inconsistent offense that shouldn't even be mentioned in the same breath of the top offenses.
Seattle comes in at 17th and they had a very poor showing their defensively, then Miami at 19th. Meanwhile, their SB opponent, Atlanta Falcons were #1 in the league putting up an insane 34.4 PPG.
All of the great SB Defenses all have one thing in common, they can rush the passer and NE isn't really great at that. While ATL isn't great at that either, they have someone who can consistently do it in Vic Beasley. I understand Bill is going to come up with something and surprise us, but ATL has someone of a brilliant defensive mind in Dan Quinn who knows how to limit(Not stop) top NFL offenses.
