We also can't assume Seattle picks up where they left off or that Jacksonville isn't a fluke. Pittsburgh is going to be mediocre and won't beat NE again at home like that again. The only way Buffalo wins is if Cook goes wild like he did in their last meeting.
Opening night is going be a better matchup for NE being healthier and the addition of Brown than the Super Bowl. If Campbell shows the injury was a fluke and the OL plays better, I could see NE pulling off an upset. Seattle lost their first game to SF in week 1 last season.
I stand by 2-2 being their record at worst which isn't bad considering they are playing 4 straight playoff teams including one Super Bowl team from 2025 in the first four weeks.
