Christmas is all about traditions. The decorating of the tree, the unwrapping of gifts, Cousin Eddie, the NBA on T.V. The pillars of the holiday are Clark W. Griswold and the chance to overindulge on basketball. Though two months old, most consider Christmas Day to be the unofficial start of the NBA season. The league takes full advantage of its ownership of the day by showcasing the best players and rivalries to viewers who may be tuning in for the first time. So whether you’re trying to catch up on the happenings in the league over the first quarter of the season, or looking for something witty to say to your family while the games play in the background during the unwrapping of gifts, here’s a preview of the Christmas Day games and an abundance of Christmas Vacation GIFs to help describe them.

Boston Celtics-Toronto Raptors
The day kicks off with the defending champs playing host to the Celtics, two Eastern Conference teams on the periphery of the title conversation. Boston’s young, talented forward duo of Jayson Tatum and Jaylen Brown, after disappointing seasons a year ago, are thriving once again. Both are in the conversation for All-Star game spots. Gordon Hayward has returned to All-Star form as well despite missing time with injuries. The biggest change, however, has been the switch from Kyrie Irving to Kemba Walker at point guard. Irving is enigmatic and aloof. He clashed with his young teammates and struggled in a leadership role. Enter Walker, a more affable leader only looking to win after many disappointing years in Charlotte. The fighting and backstabbing has ended in Boston and the Celtics have the toughness to compete in the playoffs with Eastern Conference behemoths Philadelphia and Milwaukee. The Kyrie hate lingers in Boston, however, and is holding them back. They need it off their chests once and for all.

After winning the title, then losing Kawhi Leonard, most expected the Raptors to free-fall, even enter tank mode. Strong leadership from Kyle Lowry, Marc Gasol, and Serge Ibaka, combined with Fred VanVleet’s ability to carry over his success in last year’s Finals has kept Toronto in the Eastern Conference mix. The reason for the Raptors’ early season success, however, is Pascal Siakam. He’s replaced Leonard as a legit MVP candidate, averaging 25 a game and playing elite defense. Siakam is torching the league.

Milwaukee Bucks-Philadelphia 76ers
Presumptive Eastern Conference finalists before the season, the Bucks have buzz sawed through the league. At 26-4 they’ve blazed out of the gate, owning the best record in the league without the help of a non-caloric silicon based kitchen lubricant.

Giannis Antetokounmpo is dominant. The obvious MVP choice to this point, he’s added the 3 ball to his game, shooting it at 34% on the season. He hit a career high 5 to defeat the Lakers last week. Bucks fans shouldn’t take him for granted.

The Sixers defense is smothering, as expected. Joel Embiid, Al Horford, Ben Simmons, and rookie Matisse Thybulle are all above average defenders. Philly’s offense, however, is, uh, clogged.

Embiid is the league’s most dominant smack talker, despite promising in the off-season to curtail his trash talking. After clashing early in the season with rival Karl Anthony-Towns, leading to a semi-wrestling match, it’s clear Embiid is a dog with a bone.

Houston Rockets-Golden State Warriors
After Klay Thompson’s ACL injury in the Finals, losing Kevin Durant in free agency, and trading Andre Iguodala, Steph Curry broke his hand early in the season and will miss at least two more months. The Warriors are a shell of themselves, a team gassed and torched after five straight Finals appearances.

Draymond Green is the only healthy reminder of what the Warriors were, and he’s slogging through the season, watching DeAngelo Russell jack up shots and a slew of journeymen and rookies desperate to find a home in the league. With the worst record in the NBA, it won’t get any better for Golden State.

The Harden-Westbrook marriage in Houston is proceeding as expected. Westbrook has taken a backseat to James Harden, allowing him to control games with his over dribbling, foul drawing, step back three taking style. It works, however, as Harden leads the league in scoring, posting an eye-popping 38.8 points a game. Viewers hate watching the Rockets, yet Houston doesn’t care what the rest of the league has to say about their style.

Problems will arise in the playoffs, however, if Westbrook can’t improve his 3 point shooting (23.7%). Playing off the ball, Russ will have to hit open jumpers behind the line to keep defenses from packing the lane.

L.A. Clippers-L.A. Lakers
Christmas’ marquee match-up, the two L.A. teams have hoarded top end talent and, along with Milwaukee, are the three teams most likely to raise the Larry O’Brien trophy in June. A duel of Kawhi Leonard and Paul George vs. LeBron James and Anthony Davis is the best the league has to offer.

They’ll battle throughout the year. The Clippers, with Leonard and George, along with Patrick Beverley, have three of the best individual wing defenders in the league, and can shut down anyone defensively. Leonard proved his chops in last years’ playoffs and, despite some load management criticism, may still be the best player in the league come June. LeBron took offense to his torch being passed to Kawhi last off-season, however, and has teamed with Anthony Davis to form one of the best duos in the league’s history. If LeBron stays locked in and AD continues his MVP-type season, the Lakers are title favorites regardless of their so-so supporting cast. The rest of the league would love to rid themselves of these two juggernauts.

New Orleans Pelicans-Denver Nuggets
An attempt to showcase rookie phenom Zion Williamson by the league backfired as Zion’s knee injury lingers. The Pelicans, expected by many to push for a playoff spot, have floundered without the first overall pick. Many thought the rest of the roster would tread water until his return, but other than Brandon Ingram (averaging 25 a game) New Orleans has disappointed.

At first expected back by mid-December, the wait for Zion’s debut continues. Some reports have him returning after the All-Star break; others say he’ll miss the entire season. Fans’ frustration continues to mount, eagerly anticipating the debut of the best talent to enter the league in a decade.

While most of Denver’s roster worked out during the off-season in hopes of a run to the Finals, their MVP candidate, Nikola Jokic, took on all comers at the dinner table.

Jokic has been working his way into shape over the first two months of the season while his teammates have kept the Nuggets afloat, currently 3rd in the West. Denver is young and talented, but the road in front of them is steep. Without more from Jokic, rookie Michael Porter Jr., or a significant trade, a match-up against either L.A. team in the playoffs won’t end well.

Here’s hoping everyone has a joyous Christmas season. Happy Holidays and much success for all in 2020!
