What have you done for me lately?

It’s more than the title to a 1986 hit by Michael Jackson’s little sister. It’s our mantra. It’s our national anthem. It’s what many sports fanatics from all corners of this sports-crazed country are asking over and over these days.

Whatever happened to somebody just having a bad game? Forget it, loser. That’s not allowed anymore.

In Week 1 of the NFL season, Kurt Warner of the Arizona Cardinals stunk it up in a home loss to San Francisco. If you’ll recall, Warner’s previous appearance was in the Super Bowl against Pittsburgh, where he nearly guided the unheralded Cards to a world title.

But after he struggled against the 49ers, many fans questioned whether Warner had finally lost it. He was too slow to sniff out a blitz, too old to throw the deep ball.

All Warner did in Week 2 was complete his first 15 passes against Jacksonville, finishing 24-of-26 for 243 yards and two touchdowns, with no interceptions.

You could say he’s been pretty good … lately.

This is our society. It runs on 24-hour news cycles. We hang on the words of those blabbering idiots on CNN and Fox News, who spread their imbecility nonstop in an effort to infiltrate our poor little overloaded brains.

Let’s add ESPN to the heap.

When Kansas City quarterback Matt Cassel turned in a subpar performance in a loss to the punchless Raiders last Sunday, the Mother Ship wasted no time speculating whether the Chiefs overpaid for Cassel. The USC product was traded to K.C. by New England after playing well in the absence of an injured Tom Brady last season.

Let’s get this straight. Cassel played for the Patriots. Now he plays for the Chiefs. Case closed.

Find the guy some blocking and get back to me in three weeks.

ESPN also piled on Dallas quarterback Tony Romo, who played like Jessica Simpson in a loss to the New York Giants on opening night at the new Cowboys Stadium.

Is Romo overrated? Is he a bust? Does he deserve to follow in the footsteps of Roger Staubach, Troy Aikman and other Dallas quarterbacks who’ve actually won a playoff game or two in their glorious careers?

What else are the Cowboys supposed to do? Start Jon Kitna?

ESPN and other major media outlets get fans riled up over nothing because that’s what we want.

It’s more fun to be impatient and critical than to simply sit back, take a deep breath and wait ’til next week.

When Seahawks quarterback Matt Hasselbeck went down like a wounded elk at San Francisco last week with those rattled ribs, it took less than 24 hours for the “we should have drafted Mark Sanchez” talk to begin.

Yep, Sanchez has looked solid in the Jets’ 2-0 start. But what about that porous Seattle defense that needed an injection of speed, energy and toughness? I don’t recall a huge protest when the Seahawks drafted Aaron Curry, an All-American outside linebacker, with the No. 4 overall pick.

The knee-jerking must stop. Hasselbeck will return. It’s not like they had to amputate his right arm.

In college, the quacker backers down in Eugene are ready to chase Oregon quarterback Jeremiah Masoli out of town because he completed 4-of-16 passes for no touchdowns and an interception last week against Utah.

Forget that he rushed for two TDs in the Ducks’ 31-24 victory. Forget that he threw for 2,123 yards and 13 TDs last season. Forget that Oregon has a 2-1 record.

What has Masoli done for Ducks fans … lately?

Oregon has a new head coach. Its offensive line is inexperienced and, well, not very good. The last thing that team needs to do is blow up its offense.

At Oregon State, there is talk of starting QB Sean Canfield getting benched in favor of Lyle Moevao, despite the fact that OSU is 2-1 after losing to a quality Cincinnati team last week.

None of this second-guessing is surprising. Gone are the days when we bathe our teams in unwavering support.

It’s always somebody’s fault. And Mr. Somebody must pay.

How ’bout we all just back away from the panic button and allow somebody to simply have a bad game?
