Proven whom wrong ? And based on what ?
Andy is entitled to his opinion, but unless he can predict the future, he has not proven anybody wrong yet.
And for someone who claims again and again that football is the ultimate team sport, and statistics are mostly useless because it doesn't account for situational football, his main (and only) point is the 17.9 ppg of this defense, saying that the team defensive PPG is the defense contribution to the team 9-2 record. Problem is, for someone who says that some stats are useless because it doesn't reflect situations, he quickly discounted the impact of the offense and the special teams on the Pats defensive PPG. When he was told that the Pats have the best starting position of defense (the results of a stellar offense and special team), he discredited this argument completely. Heck, the defensive PPG includes kickoff and punt returned for TDs, and pick-6, and the Pats have been exceptional on all these aspects.
It's easy to 'win' an argument when tossing out the facts that run against your opinion. So unless someone can provide me with clear data that shows only the contribution of the defense to the team overall record, I'll keep my doubts that this defense can win a game if the offense falters in the playoffs. Efficiency numbers are much more valuable in evaluating the defense, because these are not statistics that are related to offensive or special team performances, while the PPG is greatly impacted by things the defense has no control over (such as a turnover on their own side of the field).
Hey, I want the Pats to win as much as Andy does. But I'm not blind either : when I see Belichick trade Collins in the middle of the season, I understand he's not happy with the defense. And I trust Belichick's judgment a whole lot more than anybody posting here. Fact is, who here was seeing Collins as an average LB just before the trade ? Yet, since the trade, I don't see anybody here or on TV praising Collins that much anymore...
