The thing is that if the Mavericks wanted to improve defensively to better their championship aspirations, the goal should've been keeping Luka and bringing in pieces to accommodate him and Kyrie, not trading the cornerstone franchise player just to get better defensively; that doesn't make any sense.
This was an idiotic subtraction-by-addition move.
It kinda makes it seem like they valued Kyrie more than Luka, which is crazy; sure, Kyrie is still playing great, but even then, he's not the reason why you made it to the finals or had a championship window, he's apart of it but not the defacto reason.
The fuked-up part is that the Mavs are acting like the return to the finals is a sure thing for them when they're dayum near dropping in the standings halfway out of Play-In contention. They better hope they even make the Postseason at this rate and hope Irving and AD don't catch a bad break from the injury gods cause if one, or worse, both of them, go down for an extended time...shyt.
