Go.Pack.Go, you carry this torch after every narrow Packers win, and it's just as illogical after this close win as it is after every such win. Yes, it worked out in the end (though may I remind you the Packers required a virtual MIRACLE to ice this game in the very last minute). Yes, they got the victory. But does that absolve the team of the mistakes they made? Absolutely not. If anything, it raises the urgency caused by these mistakes. Sure, it all worked out in the end, but those very same mistakes could easily kills the Packers' chances in the next game (what's their record in close games again?) against a team that plays nearly flawless ball at home. The negative trends need to be fixed -- yes, even during victories -- because they tend to rear their ugly head with irreparable consequences at the worst possible times.
If the Packers were steamrolling through their competition, your point might have more validity. But the fact that the Packers are objectively LOUSY in close games shows that calling them on their poor fundamentals and undisciplined plays is more than justified. And scoffing at people who point out those problems makes you look like an out-of-touch idealist.
Yes, the Packers won. Yes, we're happy about it. That doesn't mean there aren't some highly concerning things that happened in this game that could easily doom them next week.
