First of all, please show where I said that the Pass defense was great. You can't because I didn't. Secondly, people who ONLY look at the stats, the way YOU are doing are missing most everything. Like the actual games themselves.
Next, here is some reality for you. After the first four games last season, here are the pertinent stats from the defense.
Passing Yards Allowed: 1507 (avg of 376.75)
Rushing Yards allowed: 431 (avg. of 107.75)
Sacks: 6
Interceptions: 7
Using your "ON PACE" method of judging things, this is how it would have been:
Passing Yards allowed: 6028
Rushing Yards allowed: 1724
Sacks: 24
Interceptions 28
Here is what REALITY was:
Passing Yards allowed: 4703 (293.5 avg)
Rushing Yards allowed: 1874 (117.125)
Sacks: 40
Interceptions: 23
Can you see the differences? The Pass defense improved significantly. The rush defense took a slight step backwards.
So, currently, the Pats are doing BETTER than last year's numbers allowing 281.5 passing yards per game and significantly better against the run.
The Pats have had a significant change over on their D-line with Carter and Anderson moving on and Jones and Ninkovich taking over. Not to mention the Pats moving to the 4-3 almost exclusively. They also have 3 new safeties in Wilson, Gregory and Ebner (two of whom are rookies).
So, you'll forgive me if I'm not all doom and gloom like yourself and making claims that just aren't supported by reality. I can fully understand that this defense gets better as the season goes along. That the players GEL. That the rookies get better as they learn the system. That the veterans who are new to the system get better as they adjust to the system.
YOU, Bassman, are the one with your head in the sand, refusing to see reality. The NUMBERS clearly show that.
