A total of 11 NFL teams have jumped out to 2-0 starts, tying the league record for the most in a single year. While it’s still early, a hot start normally bodes well for postseason implications. Since 1990, of the 244 teams that have opened the year with 2-0 records, 151 of them (61.9%) have made the playoffs. On average, those 2-0 teams have gone on to post 10-6 records, and 19 of them went on to win the Super Bowl. 

Some of this year’s unbeaten teams certainly appear to boast Super Bowl potential. But there’s some fool’s gold in this bunch.

Here’s a look at which teams to believe in, and which squads to pump the brakes on. 

Believe in: The Kansas City Chiefs. There’s no complacency in this bunch after winning their first Super Bowl in 50 years. Patrick Mahomes again looks like an MVP candidate, and a potent offense just might be even more well-rounded thanks to rookie running back Clyde Edwards-Helaire.

Pump the brakes on: The Las Vegas Raiders. Has the move to Las Vegas invigorated an offense that struggled to score last season? The Raiders are averaging 34 points per game, fourth most in the NFL. But is that sustainable? Inexperience, particularly at receiver, eventually will hurt this team. And the defense is yielding 6.7 yards per play and a 58.3% success rate on third downs, both worst in the league.
