Porn Star Richelle Ryan Will Fix Odell Beckham

Could a big-assed porn star save Odell Beckham's season?

Richelle Ryan sure seems to think so ... and the NY Giants superfan is making a plea to the embattled wide receiver to give her a shot.

Ryan -- star of 'White Booty,' "I Like Phat Bunz 2" and "Plump Rumps" -- says she's sick and tired of seeing her team lose and wants to take all matters into her own hands.

"I can tame that kid a little bit, I think."
