I think there's a hint of being personal on Luka's side although I have seen him being a sport after the game.
There was even a time him chasing Booker while he is near the exit just to shake his hand.
Dallas Mavericks is strong but it had always been the closing of the game that makes me worry. Today against the Suns, they did better by not letting them get near the lead they worked hard for. It never went down to 15 point lead for the last 3 quarters.
Every player contributes especially the tenacious Josh Green who is doing so much on both ends of the floor. Fans love him for his energy.
Luka Doncic always took it personally but let's all admit that Luka Doncic is really remarkable player and many NBA legends have said to Luka, that he is a genius that could see the whole court an elite passer and get the ball inside whenever he wants to or shoot a three, Luka Doncic might have that slow pace movement but he can be at the right place in the court to make his score, that is how good he is, but for the recent Phoenix Suns back last season it really gets personal for Luka to roast the Phoenix Suns that way,
To be fair Luka getting it at this age would be proof of 2 things. First of all, any team who passed on him made a huge mistake, that is already known to be fair, but it was obvious even at that time, but would be confirmed now as well.
Secondly, Dallas needs to do a better job surrounding him with better players as well, this kid has been around for just a few years now, and already playing like he would win a championship if you just put the right pieces around him, and that is a big deal, not many people can do that, not at that age at least. He should be given a bit of talent around him, maybe another star, so that he could win the title and his talents wouldn't go to waste.
They could surely put the best pieces around him but I guess the chemistry is not yet established there are great players in the Mavericks that didn't see their worth on the Mavericks because Luka Doncic overshadowed them, but as Luka has said he doesn't need to wait for them to progress on the team, they need to know their worth inside the team and what they could contribute,
