Five observations on the fourth weekend of the 2017 NFL season:
1. The 1972 Miami Dolphins can start putting the champagne on ice. With the season only four weeks old, Kansas City is the only unbeaten team in the wake of the Chiefs’ 29-20 victory over Washington and Atlanta’s 23-17 loss to Buffalo.
By contrast, there are four winless teams – the Cleveland Browns, New York Giants, San Francisco 49ers and Los Angeles Chargers.
The odds, though, are against the Chiefs going unbeaten. They barely escaped with the victory over Washington on a field goal with four seconds left. They added another touchdown, recovering a fumble on the last play when Washington tried the Stanford band lateral play.
That enabled the Chiefs to cover the spread and the over so a lot of money changed hands on that last play. But looking at Andy Reid’s playoff record – only one Super Bowl appearance and an overall 11-12 mark — it is too early to crown them as a favorite to make it.
