Adem Bona's Foot Sprain Just Reopened the Only Real Hole in Philly's Superteam

The news landed Thursday: Adem Bona suffered a sprain in his left foot and will be re-evaluated at the start of training camp. On most rosters, that's a footnote. On this one, it's the most revealing thing that has happened in Philadelphia since LeBron James signed.

Because the 76ers spent the offseason eliminating weaknesses. James arrived in free agency, Jaylen Brown via trade, and both join Joel Embiid, Tyrese Maxey and VJ Edgecombe in a starting group that has turned Philadelphia into one of the league's most discussed teams. The market has noticed: betMGM lists the Sixers with the third-shortest championship price in the NBA, behind only Oklahoma City and San Antonio, with a season win total of 50.5.

The exception to all that star power is the stretch of every game when Embiid is on the bench.

Embiid played 38 games last season, averaging 26.9 points, 7.7 rebounds and 31.5 minutes when available. Bona was the insurance policy behind him: 71 games, 17.4 minutes, 4.8 points, 4.3 rebounds, 1.2 blocks and 59.5 percent shooting. Not a star. But a known quantity entering his third season, and one who had reportedly been on track to lock down the backup job.

Behind Bona is Ariel Hukporti, who logged 54 games and just 9.3 minutes a night last season while averaging 2.2 points and 2.9 rebounds. There's a case that Bona's absence opens preseason run for Hukporti and gives the Sixers early answers about what they actually have. There's also a case that Philadelphia is now staring at training camp without any tested option behind a center who has never been reliably available.

The timing compounds it. Media day is Sept. 28, camp opens the next day, and the center market around the league isn't offering easy outs — injuries to Mark Williams in Phoenix and Henri Veesaar in Atlanta have complicated the pool of available bigs. Philadelphia has kept a roster spot open, widely framed as positioning for the buyout market, and names like Kevon Looney have surfaced as speculative trade possibilities. Those are midseason levers, not September solutions.

This matters more for the Sixers than it would for most contenders because their regular season margin for error is thinner than their roster suggests. Last season's 45-37 record came with a point differential of minus-0.2, and the finish was ugly: over the final ten games, Philadelphia won four, posting an offensive rating of 112.2 against a defensive rating of 120.3. Recent-form metrics were worse still. A team that finished essentially even can't absorb many lost minutes in the middle.

None of this is a reason to panic. Bona's sprain has been characterized as something the team may have dodged the worst of, and a two-time champion was already added to the camp roster for depth purposes. But the Sixers built a superteam around a 7-footer who has appeared in fewer than half his team's games in each of the last two seasons, and the cushion behind him is now a third-year center in a walking boot and a fourth-year big with under 10 minutes per game of NBA experience.

The championship odds say Philadelphia belongs in the conversation. The depth chart says the conversation depends entirely on whether Embiid stays on the floor — and whether anyone behind him is ready if he doesn't.
