Herschel Walker -- Sorry Madden Curse ... Odell Beckham Jr. Is Gonna Own You

How good is Odell Beckham Jr.? So good that NFL legend Herschel Walker thinks he can defeat one of the most powerful forces in the history of sports ... the dreaded "Madden Curse."

Walker -- who is kicking the hell out of father time we must say -- was out in NY when we asked if Odell's 2015 season was in jeopardy ... since he's the coverboy for Madden '16.

If you didn't know ... some believe gracing the cover of Madden comes with seriously bad juju ... with athletes like Shaun Alexander, Daunte Culpepper, and Donovan McNabb suffering tragic injuries the same year they did it.

Check out the clip -- Herschel's heard of the curse but he basically thinks nothing ... not even supernatural forces ... can stop the force of nature that is Odell Beckham Jr.
