I just took a break to read this

So you’re in a fantasy football league.

Could you and other would-be coaches and general managers be costing American businesses $7.4 billion this NFL season?

Somehow, we doubt it.

A study by the Chicago outplacement firm Challenger, Gray and Christmas came up with that estimate by assuming 13.6 million fantasy football players making an average of $80,000 a year spent 10 minutes a day on the job managing their rosters.

Forbes.com writer Tom Van Riper -- who probably checks the NFL injury report when he has writer’s block -- isn’t buying it, either.

“Hopefully, U.S. companies are grateful to have these numbers tallied for them, since clearly no employees ever engaged in any downtime on the job prior to the days of the Internet and fantasy sports. How managers must long for the days when no workers ate lunch, used the restroom, chatted around the water cooler or ran an errand during a typical eight-hour day. . . .

“Those 10 minutes spent in the bathroom today? That just cost the company $6.40, plus a bigger water bill.”

Here’s an idea for Challenger, Gray and Christmas to improve productivity: Quit sponsoring lame studies -- although before this item most readers had probably never heard of Challenger, Gray.

Maybe the joke’s on us.

Trivia time

Off the top of your head, please, name the three remaining winless NFL teams.

Block that interest rate

The NFL and Visa have produced an interactive game called “Financial Football” that allows players to pick an NFL team and try to score by correctly answering questions about such things as interest rates, mortgages and simple financial calculations.

We found it at www.practicalmoneyskills.com.

What we didn’t encounter: any questions about the how insanely high your rate might soar if you accidentally make a late credit-card payment.

Paper trail

While investigating some outlandish expenses the Yankees submitted to the city of New York for reimbursement under a provision to deduct stadium “planning costs” from their city rent, the Village Voice stumbled across a list of hotel pseudonyms used by Yankees players and other personnel on the road in 2005:

Mike Mussina -- Simon Phoenix

Don Mattingly -- Bruce Almighty

Ruben Sierra -- Austin Powers

Derek Jeter -- Johnny Drama

Jorge Posada -- Ricky Ricardo

Censored by the L.A. Times: The pseudonyms for Bernie Williams and Luis Sojo.

And the pseudonym for Reggie Jackson, one of the all-time do-you-know-who-I-am guys in the game?

Reggie Jackson.

Maybe it was Gravity

Saxophonist Kenny G, who played in the Nationwide Tour event in Rancho Cucamonga last week but missed the cut after rounds of 78 and 82, recounted missing a putt when it broke left after he watched a playing partner’s break right.

“So that was weird,” he said. “I sound like a golfer, don’t I? ‘It’s not my fault. It’s the greens.’ ”

Trivia answer

Miami, St. Louis and New Orleans.

And finally...

Alyssa Milano, the actress and Dodgers fan who is working for the TBS Hot Corner on MLB.com during the playoffs, told SI.com she gets weary of people bringing up the different baseball players she has dated or is rumored to have dated.

“You never want to relive past relationships,” she said. “But I get it. I’ve also been very vocal in feeling that there’s an incredible double standard going on that we think Derek Jeter is cool because he’s dated lots of actresses.”

Touche.
