I have no idea what they use to predict the outcomes but "ESPN Matchup Predictor" says we have a 59.4% to win and 40.6% for chiefs. I'd be curious what inputs/variables they're looking at
Yards per play vs yards per played allowed, adjust for nfl average adjusted for opponents played. Factor in probability of turnovers and 💥.
you then take the expected points per game for each team and feed it into a Possion distribution for each possible out come and count up the probability.
thats the base formula, obviously vegas has it tweaked over the years.
I was curious back in 2019 so I tested how accurate Vegas was on their probabilities. I took 6 years of games and calculated out how often the teams won against their probability to win (moneyline value).
and the result was the following:
Team with 90% prob won 90% of the time
Team with 80% prob won 80% of the time
Team with 70% prob won 70% of the time
Team with 60% prob won 60% of the time
…. And so on
i was like… dam can't bet against vegas. I was hoping to find something like the team with 40% prob really wins 50% of the time and then I would just always lay bets on the slight dog and guarantee ROI over time.
