EAST RUTHERFORD, N.J. -- Odell Beckham Jr. will enjoy seeing his college quarterback Sunday when his New York Giants visit Zach Mettenberger's Tennessee Titans.

The two former LSU Tigers won't be on the field at the same time, but part of Beckham wishes they could be. He said he wishes he could play defensive back against his fellow rookie.

"I would love to," Beckham said with a smile after Giants practice Thursday. "I would probably get a flag, because I would taunt him if I got a pick-six. Hopefully one of my teammates can do it for me."

Giants defensive coordinator Perry Fewell's eyes lit up at the thought.

"No question. That's no joke," Fewell said of whether Beckham could play defensive back. "I tried to recruit him back in camp when he was out with the hamstring injury. I think he could be an excellent cornerback."

Banged up as the Giants are at the position, that's still not a consideration. Beckham will be on the sideline when Mettenberger is trying to move the ball against the Giants' defense Sunday. And Beckham believes it will be a tough test for the Giants.

"He's as tough as they come," Beckham said. "He's going to sit back there and take all the hits, he's going to step into it, and he's going to make the throws. I loved having him as a quarterback, a guy who's out there talking and things like that. He's going to be a great one."
