Mayfield won't reveal contents of RV for Browns' QBs

It's the biggest mystery at Cleveland Browns training camp: What's in the RV?

The RV in question was spotted parked at Browns practice last week, and it was later learned that it's meant for Cleveland's quarterbacks.

But when rookie pivot Baker Mayfield was asked for more details of what's inside, he wasn't ready to share.

"Privacy in my home, my mobile home," Mayfield said, per Pat McManamon of ESPN.

While the contents of the RV are still under lock and key, veteran quarterback Drew Stanton, who was the man behind the idea, said Mayfield will be footing the bill as part of his rookie responsibilities.

"The RV started back in the spring when we had the rules committee for Baker," Stanton said.

"Drew just has a list of commandments. I think if I abide by them, I might play as long as he has, so we'll stick to it," Mayfield added.

The passers also revealed that offensive linemen and skill-position players are allowed access to the RV.
