When the NFL schedule is released, the vast majority of fans do the same thing. It's virtually a contractual obligation for fans to go through their favorite team's season game by game and pick winners. It's just part of the job. I would argue that these projections are usually a tad optimistic, but part of the fun of getting excited for the season is imagining the feeling of beating your archrivals or pulling out an upset on the road. I get it.
My guess is that if we could somehow get every projection from every single person who went down the schedules of the four teams in the AFC West, not a single one of them would be perfect through three weeks.
