The NBA Cup works when rivals collide, and Knicks-Sixers proves it

Is the NBA Cup a real competition or a fun side quest with a nice trophy? Friday night in Philadelphia gives the best answer yet: it's real when the right teams are in the room, and the league should stop pretending every group game can carry that weight.

Here's the setup. As NBC10 Philadelphia notes, the Sixers host the Knicks in a game that counts both as a regular-season contest and as the opener of East Group B. The Sixers won the first meeting 106-100 on New York's banner night, and the Knicks, defending Cup and NBA champions, lost their first three games before winning two straight. Philadelphia is 4-1.

The best Cup games are the ones with a grudge attached

A tournament doesn't create rivalry. It borrows it. This game has a fresh result to avenge, a champion with something to prove and a Sixers team trying to get past Group Play for the first time. Per NBC10, Philadelphia is 5-7 across the first three editions and has never advanced.

Then there's the group itself. The Knicks, Sixers, Cavaliers, Heat and Pacers are all described by ABC7 as contenders to win the East, and every former Cup MVP is in the group: LeBron James, Giannis Antetokounmpo and Jalen Brunson. In our view, that's what the tournament's pitch should look like. Nobody needs a slogan when four games can decide who goes to the knockouts.

Four games make every possession matter, and that's smart design

The format deserves credit here. With only four group games, a bad night can sink you. Head-to-head record is the first tiebreaker, then point differential, so a Knicks-Sixers result is more than a notch in the win column. It's leverage. That's also why coaches may keep pushing in games that look decided.

The overtime rule is a neat touch too: the result counts, but the point differential is zeroed. It tells us the league understands the tiebreaker is the engine of the whole thing.

Compare that with the Celtics' path, as NESN lays it out: Chicago, Atlanta, Charlotte and Washington. We'd argue that's a far gentler road than Group B. It's the nature of a draw, and it will always make some groups feel like events while others feel like homework. The league can't fix that completely, but it should keep seeding in a way that gives us a few collisions like this one.

The stakes are still thin once you leave the knockout rounds

Here's our pushback. The Cup's incentives are mostly about the knockout stage: three group winners and one wild card per conference advance, prize money climbs by round, and there's an MVP and an All-Tournament Team. Beyond those games counting in the standings and in tiebreakers, ABC7 reports there is no playoff impact, and an idea to guarantee a playoff berth for the winner was discussed and not adopted.

We think that restraint is defensible. A guaranteed berth would invite ugly incentives and cheapen the regular season. But it means that for the 22 teams that miss the knockouts, the Cup is mostly a schedule quirk, and the league has to keep finding other ways to make those games matter. The scheduling tweaks are a start: the semifinals and quarterfinals are at home sites, and the final moves to Hinkle Fieldhouse in Indianapolis on Dec. 11. A college cathedral is a better backdrop than a neutral showroom.

The deeper test is whether fans outside the contenders care. Our guess is that they will if the league keeps stacking groups so that rivalries, star power and tiebreakers collide early. This game isn't a perfect model, since it only works because two strong teams happen to share a bracket, but it's the right direction.

Our verdict: build more Fridays like this one

Don't add a playoff berth. Don't add gimmicks. Keep the four-game sprint, keep the head-to-head tiebreaker and keep leaning on the draw to produce a few rematches with an edge. Friday's game could still be an ugly, low-scoring slog, and the early scoring from both teams suggests that's possible. But if it comes down to the final minutes, it will make the case better than any press release. The Cup doesn't need to be bigger. It needs more nights like this.
