While I don't agree much with your specific complaints re: play-calling, I agree in general people are too sensitive about critique to McD, and I agree with the reason for it - NEM's rants. Let's face it, McD is more spiritedly defended around here than Tom Brady or Bill Belichick. And I do think McD gets blame for things he shouldn't, but I also wish Brady or BB would get the same rallying cries McD does.
I think that people would not be so 'sensitive' (as you put it) to the complaints about McD, or anyone else, if there were some actual facts involved in the attackers' arguments that made sense. That's not really the case here, though. Let's break down relevant facts to this argument:
1.) We're being told that teams stopped the long passing game better as the year went on when every single game in the second half of the season featured at least one pass play that went for 40+ yards for the Patriots. Now, this is after 4 of the first 8 games had no pass plays that went for 40+ yards.
2.) Ranking the opposing defenses. First half: 19,5,18,24,21,13,30,11. Now, to add a little more intrigue to that, remember that San Diego was playing terribly at the time, and nothing like the #5 defense in the NFL. Still, even keeping San Diego's 5 ranking, that's a total of 141, which averages out to 17.625. Second half: 1,18,9,22,2,19,30,17. Now, that's a total of 118, which averages out to 14.75. So, teams in the second half were better defensive teams than the teams in the first half. Why should anyone be surprised if there was a corresponding drop off in scoring?
3.) How many 'bad weather' games occured in the first half of the season? I believe that the answer can safely be credited as 0. That was not the case in the second half, which also impacted the scoring totals and deep game. Anyone wishing to argue that this is not true need only to watch the second Jets game to realize their error.
4.) Brady was hurt in the San Diego game and clearly wasn't back to 100% in the Super Bowl. Unless McD is the one who injured Brady, the O.C. shouldn't be shouldering blame for Brady's lower quality of play. After all, for example, it wasn't McD telling Brady to get picked 3 times in the AFCCG, including once in the endzone on a pass that should have been lobbed to the back of the endzone, was it?
5.) There's even an argument that the problem was a lack of passes going 21+ yards
in the air to players other than Moss, even though I've already posted the numbers disproving that as well.
6.) There's also an argument that because Stallworth didn't get more passes going 21+ yards in the air, he was somehow misused. This argument overlooks two obvious points, of course. First, it's just someone's opinion that he was being misused, and the record setting point total amassed by the team pretty much puts an end to that notion. Second, Gaffney (who had 5 such passes) was getting some of those passes as he took snaps away from Stallworth, and Stallworth did have 4 of those 'long' catches to Moss' 11. Some people remember the Brady-Moss-Brady-Gaffney pass. Apparently, those complaining about the deep game missed that one. They also seem to be ignoring another notable fact: Stallworth was let go and not brought back after seeing his playing time reduced over the course of the season. Will the next claim be that Stallworth was simply made a scapegoat?
