Former Alabama running back Eddie Lacy got a tip about staying warm for cold-weather football.

As a member of the Green Bay Packers, it might prove useful, no matter how bizarre.

So former Michigan star Denard Robinson enlightened him: Vaseline.

NFL rookies got together at the Rose Bowl last month for a photo shoot where they also interviewed each other for SB Nation. The video is below.

Robinson, now a Jacksonville Jaguar, tried to interview Lacy, but the former Tide star asked Robinson "what's your methods to staying warm up there in that snow?"

"What I did was put Vaseline on, a lot of Vaseline," Robinson said.

"So the Vaseline keeps you warm?" replied Lacy.

"It keeps the heat inside your body," Robinson told him. "It closes your pores up, that's what it does."

"Well, there you have it world. Vaseline. Helps with snow," Lacy said.

The entertaining exchange is at the 2-minute mark and the 2:45 mark.
