Coming off the best season of his career and a brand new $31 million contract, how does Miami Dolphins wide receiver Brian Hartline spend the offseason?

Freezing his butt off while working at a convenience store drive-thru in his native Ohio.

And this isn't just a publicity stunt. During an appearance on the Dan LeBatard Show, Hartline was actually working at the Smart Stop convenience store that he and his friend purchased in January. It was snowing in Ohio, but that didn't deter Hartline.

"I'm dead serious," Hartline told LeBatard when asked if he was joking.

So just a few months after a season in which he caught 74 passes and broke the 1,000-yard receiving mark, Hartline is back at work. LeBatard couldn't believe it.

"[It's] the American Dream," Hartline said. "Owning your own business."

Of course, Hartline isn't the only NFLer to take up a second job this offseason. St. Louis Rams running back Terrance Ganaway has been working at Jimmy Johns, and free agent linebacker Justin Durant apparently filled out an application at Chick-Fil-A.
