Something tells me we may end up 13-3 just like that ‘99 team. And then...
Biggest concern for me right now tbh is injuries. They're the element that never gets considered too much in hindsight but they inevitably change the course of every NFL season. The '99 team had a ridiculous run of good health, hopefully this season continues the same way.
Outside of the injuries though, this team has grown like crazy game to game. So yeah I think they're capable of 13 wins, even if right now I'm waiting for the three playoff type matchups on our sched to be sure this is that level of team. Nice thing about these guys is I don't think they have a ceiling. They look like they can play with anyone and if they keep improving yeah, this might be lightning striking twice.
In the OP I was moreso asking the question than anything else since there were some similarities and it was fun to think about. Now, as this team just keeps getting better and better it's starting to look possible. Exciting stuff man, what a season thus far!
