Jets' Marshall challenges Steelers' Brown to luxury car wager

LATROBE, Pa. -- Antonio Brown is shaking off Brandon Marshall's challenge like a cornerback.

After Marshall bet a new Porsche that he'll have more yards than Brown in 2016, the NFL's reception king said the 32-year-old Marshall must need some PR.

"He too old to be doing that," Brown, 28, told TMZ Sports.

Standing in front of a white Porsche -- the new sponsor of the New York Jets -- Marshall said on an Instagram video he'll give up the car if Brown outdistances him in receiving yards, but "if I have more receiving yards than you, you've got to give me the Rolls-Royce." Brown is scheduled to drive a Steelers-inspired Rolls-Royce Wraith into training camp Thursday.

Marshall recorded 1,502 yards last season, which was 332 short of Brown's 1,834.

"The RR (Rolls-Royce) is about $100K up (from the Porsche value)," Brown told TMZ. "If he really serious, call me ... I'll gladly accept. Don't Internet it."

Perhaps Marshall should have used scoring as the criterion. Last season, Marshall caught a career-high 14 touchdown passes, four more than Brown.

"I just love competing. I love competition," Marshall said Thursday while speaking to reporters at the Jets' training camp in Florham Park, New Jersey. "There are games within the game, if you follow me. There are a few guys in the league that really take pride in their work; it's their life's work and they want to push. You always want to advance the position. You always want to advance what the guy did the year before or the generation before -- and he's doing that."

The Steelers veteran is widely considered the league's best pass-catcher after recording 265 receptions from 2014-15, an NFL record during a two-year stretch. Most reasonable fans would select Brown to win this bet.

Overall, this seems like friendly banter, but it deepens the intrigue in league-wide receiver hierarchy for 2016.

"It's just competition, it's fun, but it's personal and it's real," Marshall said.

Marshall declined to say if he actually owns a Porsche.

Jets teammate Eric Decker stayed out of the back-and-forth between Marshall and Brown.

"That's a lot of money to be throwing around, a Porsche and a Rolls-Royce," Decker said, laughing.
