The past two NBA champions meet on Tuesday, but they head into the game amid contrasting seasons to this point.

Defending champs the Milwaukee Bucks took a little time to get going but are now just half a game back in third in the highly competitive Eastern Conference.

The Los Angeles Lakers, whose title Milwaukee took, also took a little time to get going, yet they remain firmly in that rut.

A team led by LeBron James and Anthony Davis are always likely to be a threat if they can make it to the playoffs – ninth place is still good enough for a play-in – but the Lakers' remote title credentials should be given a firm examination at Crypto.com Arena.

For while the Bucks have kept together their championship-winning team, albeit Brook Lopez is out with injury, the Lakers are unrecognisable from their 2020 run.

In a bid to extend James' title window, LA's promising young players have been traded away for veterans in a series of moves that simply have not worked – Russell Westbrook's expensive arrival from the Washington Wizards chief among their missteps.

With little room for further movement ahead of Thursday's trade deadline and with the Bucks visiting having so far made light work of a tough west coast road trip, the Lakers really have their work cut out.

Los Angeles Lakers – LeBron James

James is likely to be the main man on every team he plays for until he retires, but that is particularly true of this Lakers team in this season.

The Lakers are 26-28 but 20-17 with James involved. Injuries have limited the four-time MVP's involvement, yet he is dazzling when on the floor, with 29.1 points, 7.8 rebounds, 6.4 assists, 1.6 steals and 1.1 blocks per game.

After missing five straight games with knee swelling, James returned last time out against the New York Knicks and put up a triple-double in an overtime win.

That included 29 points in a 19th straight game of scoring at least 25. Only Joel Embiid (20 games, also active) has had a better such run this season, while just once in James' whole career – 21 games with the Cleveland Cavaliers in 2008 – has he enjoyed a longer sequence. Reminder: LeBron is 37 years old.

The Bucks may be able to beat the Lakers, but the notion of any team stopping James right now feels a little far-fetched.

Milwaukee Bucks – Giannis Antetokounmpo

Tied on a live 19-game streak of 25 or more points, Antetokounmpo is performing on a par with James but without the repeated injury lay-offs. For that reason, he is among the MVP favourites once again, looking for his third award in four seasons.

For all the hype around Luka Doncic, Zion Williamson or Ja Morant, Antetokounmpo – still only 27 – remains the man most likely to take the mantle from James as the face of the NBA.

The 'Greek Freak' is averaging 28.9 points, 11.2 rebounds, 5.9 assists and 1.4 blocks and will surely relish the opportunity to come up against LeBron.

When James was missing back in November, Antetokounmpo scored 47 points (a season high) to lead the Bucks to victory. Do not rule out a repeat, even with his veteran opponent also in top form.

KEY BATTLE – AD and Portis to fight at the five?

Davis continues to switch positions on an almost nightly basis, but he is likely to line up as a center against the Bucks, who have Bobby Portis – another power forward standing at six feet, 10 inches – playing the five.

But the Lakers superstar is set to have his work cut out in what has been a tricky season so far. While he has recovered some form over the past week, so has Portis.

The Bucks man had a season-high 30 points at the Portland Trail Blazers to start this road trip and added 24 against the Los Angeles Clippers, shooting 19 for 25 across those games.

"Bobby's found a good rhythm," Mike Budenholzer said after the Clippers game. "The past two nights he's shooting it so good. He's getting some baskets around the paint, too, and doing lots of different things, the rebounding."

Whether Portis can continue to be effective on the glass, where he averages 9.1 rebounds per game to Davis' 10.2, could be vital.

HEAD TO HEAD

The Lakers have an 83-53 lead in the all-time regular season series, but Milwaukee have made a significant dent in that deficit in recent seasons.

Since the Lakers won six straight between January 2008 and November 2010, the Bucks are 15-6, most recently winning the only meeting of this season so far 109-102 in November.
