Some teams (casas de apuestas)

Serve as a guide to know how each team can perform, but they are far, far from being accurate. The different betting houses in Las Vegas present and publish the trends that exist for certain sporting events, and one of the most sought after by fans, experts or journalists is the favorite to be the NFL champion.

The list is built from several factors. One is from the sports side where the strengths of each team are analyzed, how they reinforced and the rivals they will face in the season, and the other is from the trends that occur in the bets that are made. Thus, there is a list of the favorite teams to be champions before the campaign starts and it is modified as the calendar progresses.

Injuries, low performance and surprises mark week by week each team within the playing field and in the same way, some teams fall off the radar and others appear, which also changes what is presented in the betting house.

When comparing how the bets were to be champions in Super Bowl LI at the start of the season and at this time, there are very noticeable changes. For example, the Patriots remain the main candidate to win the Vince Lombardi Trophy, that has not changed, but below them there has been a revolution of movements.
