While I respect fans feeling differently, I'm seeing a decent amount of the pats aren't ready, this isn't their time, etc. posts. The pats are a good not great team from a roster perspective. So is everyone else in the AFC:
broncos - Nix, mediocre weapons
chargers - injuries, lack high end talent
ravens - injuries, bottom 5 DL
colts - daniel jones
The bills have zero all-pros on their roster, their best defensive player is on IR & they have the worst outside WRs in the NFL. The engine of their offense is the run game as they run it more than they pass. That plays into the pats hands and they already held them to 20 points at buffalo. Chaisson didn't play either.
First ballot HOF chris jones is not the same player this year. The chiefs defense is slow at the second level. Offensively, they are heavily reliant on rice & kelce. I would expect them to put davis on kelce & treat him like a WR. The pats could beat them especially if they can get the chiefs defense at home.
I don't think people realize that while the pats might not have a superbowl contending roster it's close to the rest of the contenders in the AFC. Homefield could be the difference & their win total is currently o11.5 -150 in vegas. Their superbowl window is open right now.
