Teams this era which have had more success than the Cowboys this era without Mahomes or Brady.
NFC-
Egirls, Seattle, LA Rams, SF, Green Bay
AFC-
Denver, Indianapolis, Baltimore, Pittsburgh, Buffalo
That was easy to compile . Sure you can pick apart a couple of those but I didn’t include several others which have also appeared in a SB and overall they haven’t been as successful.
We could produce a pretty good argument that about half the league has had more success this era than the Cowboys.
I’m not sure why any fan would be so supportive of this ownership in 21st Century? They are a middle of the pack organization when it comes to football.
