Great game for him, he stepped up when it's necessary. Luka's early exit probably have chance the live betting spread, but it turns out it's just a trap after all as the Mavericks still won a game without Luka. I guess Dinwiddie needs to score at least 20 points per game to help Luka lessen the burden, because as what we've seen, we know he can do it.
They are trying but it does not happen as long as Luka is on the floor. Luka does dictate what will happen in the game because he holds the ball all the time, he can easily have a double double if he wants, and that makes him a better player. However, his teammates are not so independent as eventually they will just rely on Luka most of the time, and only in this type of occasion where we see a player showing their real potential, just like when Brunson exploded in the playoffs, Luka was out for many games that time.
