No, no you can't. It is awesome how you mention the week 3 game against Detroit, but fail to mention the week 13 game where Green Bay punted once, scored the first five times they had the ball, possessed the ball for 36+ minutes and outgained the Pats 478-320.
Yeah, the Packers won by 5 in Green Bay. They were a really good team. You could still argue the Patriots were better on offense (where they scored more points prior to a Week 17 game that didn't matter because they'd already locked up the 1 seed; they also scored way more points in the playoffs), allowed fewer points and yards on defense, and had better kicking and punting. The Patriots finished with the same record (even after punting on Week 17) and a better point differential. I stand by what I wrote.
If you want to argue GB was better than the Patriots, there's an argument there, but you said 10 points better than everyone else in the league, which seems pretty hyperbolic.
The other incredible play from that strange NFC Championship game in Seattle that this conversation reminds me of is Morgan Burnett going down after intercepting Wilson when he had 30+ yards of open field in front of him. The incredible Super Bowl that followed will always overshadow it, but next to the 98 Vikings, I don't think any team choked away a Lombardi as clearly as that Packers team did.
That Burnett play was nuts. There was also a two point play where Wilson threw just a prayer jump ball all the way across the field and a Seahawk came down with it. So much awful football by the Packers. They still would have had to beat NE though, who led the NFL in point differential. It wasn't like the Pats blowing the AFCCG in '07 and missing a chance to go against the Rex-Grossman-led Bears (or all the blown games in the Super Bowl by various teams).
That was a weird playoff where Detroit lost a heartbreaker to Dallas (when a key PI flag was picked up and never explained), Dallas then lost a heartbreaker to the Packers (that was the Dez "catch" game), then the Packers blew the game to Seattle, then Seattle blows the Super Bowl (in the AFC, you also had the Pats coming from 14 down against Baltimore twice).
