After finding his feet in the European league and producing consistent top performances, former Dallas Mavericks Forward Bentil scored just six points in the game.

Iceland International, Martin Hermannsson paced Reims in scoring with 16 points; Paul Carter fell a point short off meeting the Icelandic’s mark.
Monaco dominated all stats in the game including turnovers en route to the win despite playing earlier in the week in the Basketball Champions League.
