And we have seen that even with AD is still in the Lakers, and they are hoping that this year, he will not be as fragile, but he still got injured and so the wear and tear of AD's body is going to show in the next 2 years if I may say that.
Yes, they still have Kyrie and Klay, but still it's very different when you have the 25 year old as your franchise player and this could be the biggest regret if any of Nico if AD will be injury prone with his Dallas stint and then slowly losing his prime years as a Maverick.
It's funny that Davis played almost all the games during the previous season and half of this season, i.e. he has not been injury-prone all this time, which is unusual for him. Maybe such a long period without injuries made the Mavs management believe that trading Luka for Davis could be a good deal. Imho, the Mavs screwed the pooch on that deal.

Yes, I think it's very obvious that they have screwed up with that kind of trade sending Luka to Lakers and then acquiring injury prone AD which will be out for at least a month because of another injury. And so they also have a lot of injuries with their big man. And with that, I highly doubt as well that they can make the playoff or even to the finals whe Luka was still around.
Although the Lakers lost today to the Jazz which they beat a couple of days ago. Lebron played and Luka, but Lauri Markkanen scored 32 points and had a season-high three steals to lead the Utah Jazz. Clarkson as well scored 21 points. On the positive note, Bronny James scored 9 points, his season high.
