If Tauron Basket Liga, Poland's highest league, could award a co-MVP after the 2015 finals, Koszarek would receive the trophy together with Quinton Hosley. Koszarek was once again instrumental for Stelmet Zielona Gora which re-gained the title in Poland after losing it to Turow Zgorzelec in 2014, providing leadership, passing and scoring in clutch moments. He re-signed for Stelmet for three more years so he can end his career there and concentrate on another big goal - achieving honours with the national team. He has played for Poland summer after summer since his teenage years, and has the most caps among all active players, having competed at four consecutive EuroBaskets. He took a break from the national team for the first time in 2014 but now he's back, recharged and ready to be one of the leaders again.
