The Chiefs and Bills are the two of the best teams in the NFL
According to BetMGM, the Buffalo Bills and Kansas City Chiefs are currently the Top 2 favorites to win Super Bowl LVII this February, where they were also the two main favorites before the start of the season. In the high majority of online NFL power rankings, Buffalo and Kansas City are the highest-ranked teams in the AFC, and both are in the Top 3 of most of those rankings along with the undefeated Philadelphia Eagles.
In my opinion, the Buffalo Bills are the best squad in the NFL today, while the Kansas City Chiefs are the second-best team. The Philadelphia Eagles are fantastic but I would pick both Kansas City and Buffalo to beat them straight up, even if the game is in Philadelphia.
The Chiefs and Bills have the two best quarterbacks in the sport of football (yes, in that order), two of the Top 5-7 coaches in the NFL, and two of the most brilliant general managers the NFL has to offer. Also, they both have among the most talented and deep rosters in the league.
Outside of Kansas City, a decent amount of analysts had the Chiefs not winning the AFC West in their preseason NFL predictions, with some even projecting them to miss the playoffs altogether. On the other hand, the Bills were the sexy pick to win the Super Bowl among many members of the NFL. Today, the two are clearly the cream of the crop, not only in their conference but the NFL as a whole.
