I imagine Zeljko Obradovic as a head coach. just for fun. For you not familiar with him, he is the best international basketball coach ever, most trophies. Now realistically I doubt that will ever happen even if only him is concerned, for there would be a big chance he fails in some way and then his career is now not spotless anymore. But I can imagine him and the Kings (especially serbian friend Vlade) taking a risk. He could have appropriate assistants for the situation. Now the Kings are on a great pathway and their way is only up, so no reason to risk, but Obradovic is always only about absolute success with his teams, meaning he won Euroleague with 5 different teams, 9 trophies in 23 seasons, just 6 times not reaching semi-finals, with only team he coached not winning the championship being Benetton in the only season he coached them and finished 3rd instead. Won 380, lost 158 games so far (.706%).
Now another problem is Obradovic, as most european coaches, is way to harsh to his players. But let say he adapts. You can't get better drawn plays than his. He also used to coach Bjeli and Bogi on their last team in europe
