The league is always evolving. 2018, the Rams were the #2 scoring team in the NFL. Lost the Superbowl 13-3.
It will evolve again when it becomes clear that the single determining factor on a 53-man roster is the QB. That can't, and won't hold.
If it does, is the NFL worth watching for any team that doesn't have that top-tier QB? Because, think about it, WHO in the league right now do you think can take a team to the SB? Mahomes, Brady (couple of years left, tops), Rodgers (nearing the end), Brees is gone. Wilson (wants out of Seattle), Watson (wants out of Houston), Jackson? Allen? Herbert?
If any of the latter three can do it, that means they can beat Mahomes - and we know that good teams with lesser QBs can beat them.
If you're right, then the NFL has a big problem, an NBA-sized problem. It also means that places like this board really will be forevermore a talk-radio whine-fest than a fan forum.
And in the end, the NFL is a business.
