Calling the season the Jets had last year optimistic for this team is stupid. There is no two ways around it.
Yes, because they don't all go 20-0. The Chiefs lost to the Raiders and Broncos...and Packers last year.
The running game has no impact on winning outside of being able to exploit defenses when they go with light boxes against the passing game. Investing in the run game is wasted resources - which is why good teams don't do it.
Yes they do. No idea where you got that info from, but it's incorrect.
KC, for instance, the best good team. Just took Edwards-Hellaire in the 1st round in 2020.
SF: Just made a huge trade for McCaffrey.
The truth is the polar opposite of what you're claiming. Good teams make sure and have a quality RB. Houston just traded for Mixon. Or signed him in FA, don't remember which.
Buff took James Cook in the 2nd round in 2022.
Good teams make sure and have a good starter quality RB, and will go 1st round if they need to.
