I'm not going to argue with your "boxscore" analysis. It leads to stupid conclusions that thankfully Belichick and Pioli don't follow. I'm not saying the Pats D played well that day...but they shouldn't have been expected to play well in the 2nd half under those conditions. They did give up 32 points but were forced to defend 7 drives in the 2nd half.
They only needed to hold the Colts to fewer than 34 points and couldn't get it done. That same basic defense, a year older and less talented by most accounts, was able to get it done this season.
And those 13 points the Pats scored...
Total yards on the 3 drives netting those 13 points = 83 yards.
Starting field position = Indy 21, Indy 43, NE 46
So, the real reason the Patriots lost must be that Ellis Hobbs had an 80 yard return and the team took advantage of short fields. It had nothing to do with the Colts exploiting Alexander (10 tackles, Clark going off for 137 yards receiving) and the center of the field, for example.
2006 led to an overhaul of the offense. It wasn't good enough to get homefield advantage or close the deal in a high scoring game.
Did it really? It seems to me that 2006 led to the team returning the same players across the line of scrimmage, in the backfield, one of the two starting tight ends, and one of the two starting wide receivers. Yes, the team added 3 new receivers, but it was understood that the receiving corps was not a team strength even as the team was making it to the AFCCG. That doesn't somehow mean that it was the offense that cost the team the game. That makes no more sense than saying Samuel dropping the int led to a linebacker being drafted in the first round.
2007 led to an overhaul of the defense. Those defensive changes mentioned in this thread were necessary to deal with the flaws exposed in the SB and a few other games during the season.
That is history in context...unrevised and plain to see for anyone willing to look beyond the boxscore.
Again, what overhaul? The entire D-line is back, along with all the secondary except Samuel. Thomas, Vrabel and Bruschi are back, and Seau may or may not return. The only 'overhaul' is at Colvin's position. How many new starters do you expect to play that wouldn't have played under 'normal' progressions?
Seymour
Wilfork
Warren
Thomas
Vrabel
Hobbs
Meriweather (I think he'll get a spot, but it's not an 'overhaul')
Sanders/Harrison
That's 8 of 11 positions guaranteed to be filled with players who have nothing to do with this 'overhaul'. Samuel was going to need to be replaced in any event due to contractual status, and not due to his play.
That leaves a maximum of 2 starters as part of the 'overhaul', and that's only should Bruschi be relegated to the bench. I don't need to look at the box score. I can look at what was known before and during the seasons, and what was known after the seasons, and see that nothing surprising has happened based upon those last games.
