It’s too early to know for sure, but history may remember last summer’s United States Olympic basketball team as the most egregious and flagrant misusers of the nobody-believed-in-us card.

Seriously, that one’s going to be tough to beat. The bar is set high, unofficially, last August when LeBron James — 6-foot-8 and 270 pounds with Jamaal Charles’ speed and Magic Johnson’s skillset — said these words about the world’s best collection of basketball talent winning the gold medal:

“People said we couldn’t do this, so we wanted to prove them wrong.”

Not that we can fault the hustle. The no-respect thing is a staple of sports, from Olympic basketball stars to professional football players and all the way down to Little League. It’s fun, with just enough of an edge. It’s a just-add-water rallying cry for any locker room, even if coaches sometimes have to ignore praise and exaggerate slights to provide any semblance of legitimacy.

But in all of the proud history of they-said-it-couldn’t-be-done statements, there may not be anything quite like these Chiefs:

A 9-0 NFL team talking about being overlooked.

And having a point.

Historians of the haters-gonna-hate school of motivation may note the 2008 Titans, who won their first 10 games, but even that group of temporary overachievers never found themselves in the perhaps unprecedented position of being 9-0 and 6 1/2-point underdogs.
