He was California Dreamin’ towards the dying days of his Giants career, and now, after all the drama, after all the turmoil, after all the unfulfilled grandiose ambition, Odell Beckham Jr. catches the break of his football life.

He is OB-L.A. now, playing for the best coach he has ever played for, catching passes for the best quarterback he has played with, playing with the best team he has played on.

When the Giants drafted him with the 12th pick of the 2014 draft, he talked about being legendary.

One legendary one-handed catch made him an instant star.

It didn’t make him legendary.

Getting chased out of New York and Cleveland didn’t make him legendary.

Now he will get one last chance to be legendary.

It’s his best chance to be remembered one day as a Super Bowl champion — in a place he might as well call Nirvana.

He has a home in Beverly Hills. He has a fan and friend in the Lakers’ LeBron James.

If he can’t find happiness with the Rams, he will never find it.

This is his “Hooray for Hollywood” moment.

He is 29 years old. He has been plagued and diminished by injuries. But the carrot of a delicious multi-year contract after the season might yet be dangling in front of him if he can turn back the clock.

Don’t blow it, OB-L.A.

The hullabaloo over his signing with the Rams shows you he still has star power, and now he joins a team filled with stars. He doesn’t have to be The Straw That Stirs the Drink, and he shouldn’t feel the need to be. If he has never parroted that favorite saying of Vince Lombardi’s “Winning isn’t everything; it’s the only thing,” this is the perfect time for him to start.

And he is no longer the best receiver on his team. Cooper Kupp is the best receiver. By far. OB-L.A. will be even more of a factor with the news that Robert Woods tore his ACL Friday in practice.

His new teammates didn’t care about his baggage, his on-field issues with Browns quarterback Baker Mayfield. They want him to help Matthew Stafford chase a championship against Tom Brady and Aaron Rodgers. Beckham has never played with a quarterback with the kind of arm talent Stafford has. His new head coach, Sean McVay, is extremely relatable, and a brilliant offensive mind. Newly acquired linebacker Von Miller is a friend.

It might be a good idea for OB-L.A. to listen to some lyrics from the Bobby McFerrin song, “Don’t Worry, Be Happy”:

“Ain’t got no place to lay your head

Somebody came and took your bed

Don’t worry, be happy

The landlord say your rent is late

He may have to litigate

Don’t worry, be happy …

Ain’t got no cash, ain’t got no style

Ain’t got no gal to make you smile

Don’t worry, be happy

’Cause when you worry your face will frown

And that will bring everybody down

So don’t worry, be happy.”

Because he is where he wanted to be. Remember the October 2018 ESPN Lil’ Wayne interview? When host Josina Anderson asked Beckham if he was happy in New York?

“It’s a tough question,” Beckham said. “Obviously, I love, I love seeing the sunshine all the time. I love being in L.A. I just like that atmosphere, but this is where I’m at. I remember before games, I used to get that. I used to get butterflies, like good butterflies. I was anxious. And now when I step on the field, it’s something completely different. It’s not butterflies.”

Well, now it’s butterflies.

And remember what he said when Giants general manager Dave Gettleman traded him to Cleveland less than a year after signing him up to that five-year, $90 million contract?:

“They thought they’d send me here to die.”

He should feel alive enough now, with an elite quarterback throwing him the ball, so that Odell Beckham Sr. shouldn’t feel compelled to post anything negative on Instagram or via video about Stafford.

OB-L.A. had a talented partner in crime in Cleveland: Jarvis Landry. He has never had a partner like Kupp (74 catches, 1,019 yards, 10 TDs).

I asked Kupp, the pride of Eastern Washington, prior to OB-L.A.’s arrival, when his NFL dream began, and his answer should resonate with his new teammate.

“Probably when I was 9 years old, first time stepping on the football field,” Kupp said. “I didn’t know any of the guys. I had actually seen this group of kids and this football team practicing out in right field of my younger brother’s soft-pitch baseball game. Supposed to be watching my brother, but I went out there to watch, just like what is going out there in right field? I came back and told my dad, ‘I want to play football.’ I didn’t know that there was organized football for kids.

“I remember getting out there and just being like all the times that, you know, played football in the backyard with my dad, out at the park, just all of that stuff that we did, I thought that was the greatest thing. Like there’s even more here, being able to go out here and do it with a bunch of guys going for the same thing, all striving to go and win, a bunch of kids just all trying to execute something together. Just something really special about this game.

“I knew that first time out that this is exactly what I want to do for the rest of my life.”

This is where and when OB-L.A. can reignite his love for the game. Here’s Kupp on Stafford in the huddle:

“Even-keel[ed], calm, but deliberate, he knows exactly what he’s doing, able give any kind of cues, any kind of tips as we’re heading out of the huddle. Being able to just have that calm voice every single time — this is what we’re doing, this is how we’re gonna do it — and then just the command he has even from breaking the huddle up to the line of scrimmage. You feel good, you feel like you’re gonna be put in the right positions.”

Kupp on McVay: “I don’t know if there’s anyone that loves football as much as he does. He lives it, he breathes it. He wants to be the best. He wants to be a part of making sure that he’s putting us in the best positions time and time again. I think he runs on about five cups of coffee by about 11 o’clock it seems like. But he’s an incredible football coach.”

Kupp was helpless with a knee injury while watching Bill Belichick get the better of McVay and the Rams in Super Bowl LIII.

“It’s probably been one of the times I’ve felt the most conflicted in my life,” Kupp said. “You’re pulling for them with everything you have to be able to achieve the pinnacle of what we work for, and be able to win a Super Bowl. At the same time, just the grief, the sadness, that you don’t get to be a part of that. Both those things happening at the same time within you, it was a very difficult thing to go through.”

Kupp desperately wants to play in this season’s Super Bowl. He isn’t the only one.
