Illinois Roster Retention: Focus on Mirković and Ivišić Brothers

The Illinois Fighting Illini are beginning roster retention and recruitment efforts immediately following their exit from the 2026 NCAA Tournament. Following a 71-62 loss to UConn in a Final Four semifinal on April 4, 2026, at Lucas Oil Stadium in Indianapolis, head coach Brad Underwood faces critical questions regarding the future of his frontcourt.

Retention efforts are primarily focused on a trio of international players: center David Mirković and the Ivišić brothers, Tomislav, and Zvonimir. This group has been central to a recruitment strategy that emphasizes talent from Eastern Europe, specifically the Balkan region, to build a versatile and physically imposing roster.

The Balkan Bloc Strategy

Underwood and his staff have integrated a group known as the Balkan Bloc into the program. This strategic focus on the Balkans has yielded several key contributors who bring professional experience to the collegiate level.

The core of this international infusion includes Tomislav Ivišić from Croatia, who joined the roster as a sophomore after spending three seasons with the Montenegrin professional team SC Derby in the Adriatic League. He is joined by his twin brother, Zvonimir Ivišić, and David Mirković, a 19-year-old from Montenegro who also played professionally for SC Derby.

The roster also features Andrej Stojaković, who hails from Serbia and Greece. Together with the Ivišić brothers and Mirković, these players form a group that has been described as the Balkan Five, consisting of European players who all played professionally overseas before arriving in Champaign.

2025-26 Season Performance and Roster Depth

The 2025-26 season was characterized by a blend of international veterans and proven high-major players. The Illini roster combined the professional experience of the Ivišić twins and Mirković with the skills of players such as Andrej Stojaković, Kylan Boswell, and Rodgers.

Shooting depth was provided by players including Keaton Wagler, Humrichous, and Davis. This composition allowed Underwood to implement defensive adjustments designed to maximize the length and versatility of the retooled squad.

The effectiveness of this strategy was evident during the 2026 March Madness tournament. As a No. 3 seed, Illinois reached the Final Four after a notable 65-55 victory over No. 2 seed Houston in the Sweet 16.

Post-Tournament Outlook

Despite the deep run, the loss to UConn on April 4, 2026, has transitioned the program into a period of immediate evaluation. The focus on retaining David Mirković and the Ivišić brothers is paramount to maintaining the frontcourt strength that defined their recent campaign.

The program’s ability to maintain these relationships in Eastern Europe remains a cornerstone of its current identity. The international route has allowed Illinois to field players who are accustomed to high-pressure environments and physical competition, a mindset that Underwood has utilized to keep the team relevant on the national stage.

As the program navigates the transfer portal and roster management for the upcoming cycle, the stability of the frontcourt trio will likely determine how the Illini reload for the next season.
