The first half was the easy part, though nothing comes that easy for the only undefeated team in the NFL.
The Kansas City Chiefs are 8-0, remarkable by itself in a league where parity rules and only hapless Jacksonville counts as a sure win. It borders on amazing when you consider the Chiefs were 2-14 a year ago and so anemic offensively that some fans actually cheered when quarterback Matt Cassel left with a concussion in a home loss to Baltimore.
The Chiefs went out and got a new quarterback, a new coach and a new general manager after that. A lot of the team is new, too, with some 30 different names on this season's roster than last.
They're good, yes, because you have to be good to win eight straight games in the NFL. Defensively, they're top-notch, and Alex Smith does a commendable job managing an offense that takes few risks but makes even fewer mistakes.
Still, no one outside Missouri and Kansas talks about the Chiefs in the same breath as the Broncos, Seahawks or 49ers, all teams that have lost. They're not Super Bowl favorites in the sports books in Las Vegas, where the wise guys still aren't convinced they belong among the NFL elite.
The Chiefs have their doubters, and win No. 8 Sunday at home against Cleveland likely did nothing to persuade them to jump on the bandwagon. A mediocre team at best, the Browns were in the game until the final minutes before finally falling 23-17.
It told no one anything about the Chiefs they didn't already know. And it remains anyone's guess how deep the team can possibly go in the playoffs.
But the players are starting to believe. And it may not be long before these Chiefs finally get some believers, too.
