Fans Mob Odell Beckham Jr. At Lakers Game, Beg Star To Go To Raiders

Forget LeBron James and Kawhi Leonard ... Odell Beckham Jr. might have been the biggest star at Crypto.com Arena on Wednesday night -- at least, that's based on the reaction he got outside of the stadium, where he was mobbed by a throng of fans!!

The NFL superstar could hardly move as he attempted to make his way inside the downtown L.A. venue for the pivotal Lakers vs. Clippers game ... as people tried to get photos with him -- and recruit him to their favorite team.

To his credit, Odell handled the situation super well -- posing for a few selfies ... and even joking with our photog about his next NFL team!!

Seems the L.A. crowd wanted to see him in Las Vegas next season for some reason -- as multiple fans pled with the free-agent wide receiver to sign with the Raiders.

Once inside, Odell had a killer spot for the big game ... sitting just a few feet away from the Clippers' bench.

Unclear which team he was rooting for -- he was dressed in neutral colors -- but hopefully for him it was the Clippers ... 'cause the Lakers got smacked pretty good, 125-118.

Beckham wasn't the only celeb in the building taking in the action ... Michael B. Jordan was courtside too -- but no word if the guys ended up rubbin' elbows.
