Sonjun is a powerful and physically imposing forward for the Daegu KOGAS Pegasus, using his size and strength to dominate inside. At 199 cm and a robust 103 kg, and wearing number 24, he is built like a traditional power forward who excels in the paint. His game revolves around bullying defenders in the post, securing rebounds through sheer force, and setting bone-crushing screens. Sonjun's physicality makes him a nightmare matchup for lighter forwards, as he can consistently create second-chance opportunities and finish through contact. For Daegu KOGAS, he provides a necessary interior presence and toughness. While expanding his range would make him even more dangerous, his primary value is as a rebounder and interior scorer who can change the complexion of a game with his physical play.
