I'm not aware of any teams that face the Falcons or the Browns in half of their games..
Obviously you didn't get the point : the Broncos have played half their games against the top offensive teams, while the Pats have played half their games against the bottom ranked offensive team.
Of course it has an impact who each team is playing. Also important is when the met each other : playing Pittsburgh without Roethlisburger makes a whole lot of difference.
This is where we depart. I do not believe in comparing what you think might have happened to what actually happened on the football field. If it were that simple then every team would allow more points to higher scoring teams and less points to lower scoring teams without variation and that is not the case. Football is about matchups, situations, and scheme, not statistics. You do not know how teams will play against each other until they do. In your example, if the Raiders gashed Denver for 200 yards on the ground, how do you know Pittsburgh with Leveon Bell, even with Jones at QB would not have done better against them than SD, NO or the Raiders.
Again, you are handing your hat on defensive performances that resulted (or should have resulted) in losses.
See the point is what they have actually done on the football field. Everything else is your guess based upon flawed logic...
No, flawed logic is to argue that the Pats are great on defense, as good as Denver if it wasn't for the turnovers issues (or lack there of) based on one single statistic : 18.0 to 18.9 points per game allowed, while saying that football is about matchups, situations and statistics and completely disregarding the fact that the Pats offense (and their special teams, for that matter) is much stronger than the Broncos'.
The Pats defense has the luxury of having the best starting field position, on average, per drive. That comes from great offense and great special team play. Yet, when you look only at the PPG allowed to make a case for the Pats defense, you conveniently forget about all those matchups and situations, as you say.
Its a team game. That's a large part of the point here. Do you really think that the Patriot defense after getting a big lead and allowing Miami to put up points and yards had a worse day than the Broncos defense not holding NO on the last drive of the game, to get saved by a PAT miss?
Allowing the drives that lose games is entirely different than allowing a bunch yards and a handful of points while winning.
Again, this argument makes no sense. Either it's a team game, we look at the final results and see that the Broncos won, or we look at the ifs and whys.
But for some reason you keep looking at both. If you say that the Broncos defense couldn't hold their own against the Saints, let me remind you that the Pats defense was about to blow it against the Dolphins. The Dolphins scored 3 TDs on 3 drives, and got within 7 points with 6:06 to play. The Pats offense had to save the day, taking 5:02 from the clock with a 54 yard-drive. I don't consider giving up 21 points in 21 plays, and letting the other team come within 7 points of tying the game with more than 6 minutes to play ''garbage time''. The interception at the end of the game was the results of the Pats offense leaving the Dolphins with only 1 minute and no timeout, not because the defense did it by themselves.
The difference is that the Dolphins offense is pathetic, while the Saints offense is legitimate.
If you are basing your argument for the Pats defense greatness based on a single statistic, the average PPG, then looking at the opponents matters. Statistics are all about context.
