Really, it's so early in the season (although it does go by fast, doesn't it?) and so much can happen on any specific team that yakking it up about post-season appearances can only be viewed as simple good fun. Let's get to week 12, then the trash talk will begin to have some meaning ....
Certain cities have different expectations. For example, NY, Philly and lately Boston .... simply getting into the post season is not a successful year to fans here, and that goes for football, baseball, basketball, hockey, whatever ... The only thing that matters is the ring, anything less is not acceptable and is viewed as a bad season. Gotta believe that Dallas falls into that same bracket, too.
For some towns, getting over .500 is considered a success. If the Giants go 9-7, Coughlin is fired. If the Browns, Chiefs or Rams post a 9-7 record, everybody gets a raise and starts talking about how great they'll be the next year.
It's all a matter of perspective, winning cultures demand only the absolute best, whereas generally less successful franchises take the rare moments of glory to heart. And while there might not be a "dominant" team right now (Patriots are the only ones in recent years), it's very clear that there is a dominant group of franchises that by and large are successful. Every now and then an outsider strolls into the group (like the Bears did for a while in the late '80's), but overall it's the same teams, year after year, that are EXPECTED to win ...... lately, Patriots, Steelers, Colts, Giants, Eagles, Cowboys .... just a fact of life ....
