Predicting 2018 Vegas win totals for all 32 NFL teams

With the NFL down to its final four, 28 of the league's 32 teams are already thinking about next season. Of course, it's too early to have a strong sense about what each team's roster construction will look like. To do this, I'm using their performance from the 2017 season (and years past), applying whatever I learned from living in Las Vegas for a year and talking to bookmakers during my time at Grantland and making various assumptions about what each team will do during the offseason.
