I would have to say the AFC West is the best without a doubt. KC always plays well. Denver's acquisition of Russell Wilson makes them more competetive. Las Vegas gets a playmaker in Adams. LAC pairing of Mack and Bosa makes for a tough defense.
Weakest Division- NFC East or NFC South. Neither are really competetive top to bottom.
