Dallas needed to win the game more but Philly won by playing the ending better. Harden returned four games later, and that had a positive effect. Embiid again plays as we know him. Dallas is in dangerous position now. They invested heavily for the season, they have to be in play-in row at least. It's sad to see a team with so much potential go through such a disintegration. Not only their superstars Dončić and Kyrie, but also the side pieces are very good. From Kleber to Wood, Hardaway to McGee, they should've been in a much better rank with this roster.
In fact there are a lot of good teams in the West and they are very close to each other besides their win rate, I can't pick any team to leave out of play-off picture. This season standing may not be determined until the end of last match.
The Dallas Mavericks have lot's of struggles since the Kyrie Irving trade.
Before they got Kyrie, they are at the 4th spot of the Western Conference. When the trade happens and got Kyrie, many knew already that it was a fail experiment though many thought that it would be beneficial for the team especially for Luka because he will now have an all-star type of player on his team. What is the expense of the Kyrie trade? Their best defensive player in DFS, their supposed back-up point guard in Dinwiddie and some draft picks. Before the trade deadline, they are already one of the worst defensive teams around the league. After the trade? They got even worse than they are before the trade. Also add the frustration that Luka is dealing on each game, and that also affects his performance on every game.
The Mavericks are now on a position that they might not enter the playoffs this season because of what's happening to them. The team already is 6-14 since they got Kyrie. There is also a chance that the Mavericks might not sign Kyrie on the off-season because he wants a long term contract like a 4-year max contract, and for sure they will not give it to him knowing his drama and controversies that he got a few years ago. They traded their best players for nothing because they might not sign Kyrie on the off-season.
The size of the team is very awful as well, so it would be beneficial for the team to get some bigger wing defenders, but looking at the free agents, I don't see any notable players out there.
