1. Because of the Steelers' overall success over the past decade - you can't deny everyone is playing us like it is their Super Bowl or a statement game. They want to prove they can beat the contender/champ. This team has never thrived after winning Super Bowls. And while we are 2-1 now, just look at the post-SB 43 season. We started off like 6-2 and then collapsed.
2. The flip side to that is you can argue things either way. You can come out and say Green Bay looks unbeatable and are 3-0 in impressive fasion, they look even better than last season,
. they have the mental toughness to repeat or make it back to the show. Or - you can say it is only the beginning of the season and they will peter off at the end while the Steelers will get slowly better and are battle tested.
3. If the offense doesn't gel - nothing else will matter.
