I mean, everyone is potential at this point. I don't think the Cowboys are as good as the Chiefs, but the best team doesn't win the Super Bowl every year, and they have the same question marks on defense as Dallas does, if not more (can't rush the passer). Outside of KC, especially in the NFC, there aren't teams with more potential than Dallas.
Consistency, or lack thereof, in previous years doesn't mean much - and outside of GB that'd be true for every other team in the NFC as well anyway.
Seattle has not had even a .500 record since they drafted Wilson. Only winning, and have been more consistent than even GB who’s had down stretches. They went 12-4 last year in a brutal division and have a very young team. They could very well be even better this year and have more potential than Dallas.
LAR just took the greatest defense on planet Earth, combined the 11th ranked offense in the league and paired them with the QB who is on pace to be the most prolific of all time (already the most passing yards of any QB through age 33). Whether or not you believe he’s at the top of the league at the position, it’s not difficulty to accept that he’s a dramatic upgrade over what Goff was doing last year… and that 11th ranked offense with Goff is the worst McVay has resided over in 6 years! They’ve got phenomenal potential this year, more so than Dallas.
TB went 11-5 last year, 2 of their losses to The NO Saints whom they conquered in the playoffs. Take Brees off that team, and Brady a year to gel with his teammates, that could very well be a 14-15 win team in a 17 game season. Especially with their defense they have a lot more potential than Dallas.
And then there’s Green Bay. They’ve won 26 games the last 2 years and have made back to back NFCCGs. If Aaron leaves, they’re a bust yes. But with Aaron they’re still at the top of the pack, as he had maybe the greatest regular season in NFL history last year. Dallas does not have better potential than them.
In a previous thread, you said you expected Dallas to make the Super Bowl. That’s not in the land of reality (at least this year)
