He said, "right now". He is not talking about what might happen in December. So I think he is right. The Eagles look like the best team in football right now. If Hurts continues to play they way he has so far, I do not see a weakness on the Eagles roster. They added the right players they needed to after making the playoffs last year.
They also have some aging players. Kelce is in his last year probably. Cox is getting old. Brandon Graham is probably at the end of his careers as well. And as we all know, once you get really good, other teams take all your free agent players that you can't fit under the CAP anymore. Maybe next year they won't be as good, but this year they look very strong.
Arguably, Miami is also the top team in football. They just beat the Bills who everyone thought was the best team.
