Regarding expecting Luka to be a tribal chief passing on the wisdom of the ages to his team (not that you said exactly this, OP), I'm not sure that goal is entirely realistic. 

No, I just expect Luka to give effort on both ends and play the game the right way. This team has lost six of eight and the last three at home. Cut out the showboating and histrionics. It's not a good look.
