Good thing about their conflict is they don't really settle in a physical violence, but they put up numbers and fill the stat sheet and outplaying each other. That's what the fans wants to see between an individual rivalry.
Phoenix and Mavs had a good game as well as the superstars for both teams. Looking forward for both of these teams in the playoffs. Hope they'll have to face each other in a 7 game series.
That's a friendly rivalry between them. No need to put physical violence or anything that will ruin their reputation. Just trash talks is enough. Even Luka said that it was nothing, but said words directly to Booker after that.
What Booker did on the final seconds of that game is kind of funny because if he really wanted to do that, he must've done it during or on the mid-game, and not when they are already winning. Well, the quote of Luka really is applicable to him. Everybody's acting though when they're up.

Anyway, these kind of dramas are what the fans are loving for. They need to spice things up, and what's the way to do it? Rivalries. Like the Jordan-Thomas back in the 80's or the Lebron-Curry rivalry when they met in the NBA Finals 4 times. Fans love these kind of rivalries, and I would love to see these 2 teams match-up again in the playoffs.
