Do the Chicago Bulls have a sleeper prospect on their hands? One who’s flown under the radar but keeps quietly impressing? The answer is yes, and his impressive play in the G-League suggests he could soon make waves in the NBA.
That player is Lachlan Olbrich, the 55th overall pick in the 2025 NBA Draft, hailing from Adelaide, South Australia. Olbrich didn’t take the typical path to the NBA, spending a season at UC Riverside before returning to Australia to play for the Illawarra Hawks, then heading to New Zealand to suit up for the Canterbury Rams, and then back to the Hawks.
As his journey unfolded, Olbrich’s name drew little attention as he was left off mock drafts entirely. Nonetheless, Chicago took a chance on the 21-year-old, 6-foot-8 center. While he hasn’t yet made an impact for the Bulls, he’s been dominating for the Windy City Bulls.
Lachlan Olbrich Is making noise in the G-League
14 games into Windy City’s season, Olbrich is averaging 20.2 points, 8.5 rebounds, and 5.5 assists per game, while shooting 60.4 percent from the field and 34.8 percent from three. No other G-League player is matching that level of production, and he’s the only player with at least 10 appearances averaging 20.0 points, 7.0 rebounds, and 5.0 assists.
What a start for rookie Lachlan Olbrich ‼️

Despite those eye-popping numbers, Olbrich has drawn little fanfare. But that’s often the reality of life in the G-League.
Even if he hasn’t drawn much attention yet, that could change soon. Two of the Bulls’ three centers are playing on expiring contracts. Nikola Vucevic remains perennially on the trade block, and at 35 years old, he likely won’t be in Chicago much longer—there’s a chance he’s moved over the next few months. Meanwhile, Zach Collins’ contract expires this summer, and Billy Donovan has even shown a recent willingness to experiment with dual-center lineups.
As a result, there’s a legitimate possibility that Olbrich cracks the rotation sooner rather than later. He isn’t necessarily the ideal center Chicago desires (he’s not a rim protector), but he provides much-needed hustle, energy, and physicality to a lineup that has often lacked all three.
Furthermore, Olbrich’s passing ability and improved three-point shooting profile him as an ideal fit in Billy Donovan’s fast-paced, five-out offense. It’s easy to envision Olbrich setting a high screen for Josh Giddey before slipping into space as a short-roller and finding either a cutting Matas Buzelis or Isaac Okoro for an easy bucket.
Although the Bulls lost their prized lottery pick to a season-ending injury, Olbrich offers a glimmer of optimism for a team fully embracing a youth movement. While he has yet to prove himself at the NBA level, his strong start in the G-League bodes well for what lies ahead.
