The MVP is playing.

So are the reigning champions, north of the border.

And out in L.A., the NBA's newest dynamic duos will square off as well.

On the 65th day of the season, with 454 games — more than one-third of the schedule — already in the books, the NBA's unofficial start date has arrived. The annual Christmas Day quintupleheader of games is Wednesday, the day where the casual fan typically turns their attention toward the NBA.

"It's going to be cool, man," said Toronto guard Kyle Lowry, who'll be making his Christmas debut. "It's going to be very cool. I've always watched it on TV ever since I was a young child. And it's going to be awesome to step foot on that floor on Christmas Day, have my family and friends around and have the whole world watching."

The good news from a ratings perspective: Four of the Eastern Conference's five best teams so far are on the schedule, all playing each other. The bad news: The two worst teams in the Western Conference so far are also on the schedule. But LeBron James and Anthony Davis' first Christmas as Los Angeles Lakers teammates -- facing off against the crosstown rival Clippers -- should certainly draw plenty of eyeballs.

"It's Christmas Day," Lakers coach Frank Vogel said. "I hope everybody has a great holiday and spends some time with their families, but it's about the next opponent in front of us. We have to get a win."

Playoff-preview matchups?

The other matchups: Boston goes to Toronto in the NBA's first Christmas game in Canada, followed by Milwaukee visiting Philadelphia, Houston going to Golden State, the Lakers-Clippers contest and then a nightcap between New Orleans and a Denver team led by Nikola Jokic and off to the best start in franchise history at 20-8.

"You're always told that the best teams play on Christmas, the all-star players play on Christmas and the whole world is watching this game," said Milwaukee's Giannis Antetokounmpo, the league's reigning MVP who has even better numbers this year than he did a year ago.

The potential certainly exists for some playoff-preview matchups. It's not a stretch to think that the Raptors and Celtics or 76ers and Bucks will wind up meeting in a best-of-seven come April or May. And the same holds true in Los Angeles, where the Clippers and Lakers might be the best of the West.

The Lakers have Davis and James. The Clippers now have Paul George and two-time NBA Finals MVP Kawhi Leonard. Those two pairings shook up the league's landscape considerably when they came together this past summer, and so far with the Lakers are 24-6 and the Clippers at 22-10 neither side has much to complain about.

"I think we're good," George said. "I think we're good."

James-Davis pairing spectacular at times

The Clippers are 10-3 in games where both Leonard and George start. Davis and James are one of two duos where both are averaging more than 25 points per game; Karl-Anthony Towns and Andrew Wiggins in Minnesota are the other.

The pairing of James and Davis has looked spectacular at times already. If there was any confusion about whether those two superstar talents could work together, those questions have been answered.

"We know what the end goal is," Davis said. "And when you have guys like that, with veteran leadership, when everyone is locked in to our goal, it's easy for us to jell together."

James puts it even more simply.

"It's about getting better, each and every day," James said.

Doomed by injuries

Christmas is where last year's Lakers season went wrong – they were fourth in the West, then James got hurt on Dec. 25 and L.A. went on a free-fall out of the playoff picture. And injuries will affect some of what the league gets to display on Christmas this year as well.

Golden State has been doomed by injuries all season, with no Klay Thompson and no Stephen Curry for much of this season. New Orleans was picked to be part of the showcase day because of No. 1 overall pick Zion Williamson, who has yet to appear in a regular-season game -- his summer league was cut short by injury, and a stellar pre-season ended the same way. And Toronto is missing several top players right now, including Pascal Siakam and Marc Gasol.

But make no mistake: The Raptors have been waiting a long time to be part of NBA Christmas. Wednesday is their first time on the holiday schedule since 2001.

"It'll be interesting," Toronto coach Nick Nurse said. "I wish we had more of our regular guys playing in it, but we've got to go play the game nevertheless. So we'll see. I think it'll be fun. I'm getting a lot of messages from back home. Everybody's going to be watching."
