So now you're using two specific late game situations (one against Lebron and another against Fox which was a horrible mismatch that made no sense) to support your general argument that Luka is a terrible defender? If he was so obviously terrible wouldn't teams isolate him all game to help themselves win or stay ahead? Doesn't the same also hold true on the other end? Luka picks teams apart in crunch time (last night not withstanding)
You keep trashing the Mavs as if their situation is so much worse than the Kings yet they have a championship in the last decade. They've been in the playoffs much more recently than the Kings. They already appear to be on a faster track of rebuilding than the Kings (even though they started later). The big reason they are not in a better situation is because they devoted a couple years to Dirk's twilight which was the sentimental thing (and probably right thing) to do but not the wisest in terms of rebuilding. It just slowed them down.
Bottom line is who would you rather have Luka or Bagley?
I have never said Luka is a terrible defender. I feel like in your desperation to (I honestly have no clue what your agenda is here)... convince someone who doesn't need convincing that Luka is good, you're conflating criticism with an out-and-out character attack.
All I am saying is that Luka's defense in crunch time and clutch situations is less than desirable from a franchise player. I've made the same argument about James Harden for the last decade but his name isn't Doncic so obviously you weren't paying attention. The crazy thing is that I too wanted us to draft Luka (look at my posts pre-that draft). Apparently my saying anything aside from "LUKA DONCIC IS THE GREATEST BASKETBALL PLAYER IN THE GALAXY" is tantamount to me saying he's the next Kwame Brown, which is not my argument at all.
As I have detailed in numerous posts, I have serious issues with the Mavs decision to trade pretty much every single asset for Porzingis, who I'm not sure is going to be able to physically last until the end of his massive new contract. In acquiring Zinger (and subsequently extending him), the Mavs also took on a bunch of useless contracts while losing all their draft picks of worth (the best way to acquire cost-controlled talent). By the time those contracts come off the books, the Mavs are going to have to extend Luka, meaning they won't ever really have all that much money to play with in free agency. Even if they did, Cuban and Carlislie's tendencies to be blowhards (in the case of Cuban, occasionally saying dumb semi-racist things that draw the ire of most of the league or denying knowledge of a corporate culture of sexual harassment despite every sign pointing to the contrary) tends to be a deterrent to actual impact players (The Mavs have had to massively overpay to acquire free agents over the past decade). Yes, they've acquired two potential star pieces in Luka and Zinger. Unfortunately, they've also sorta backed themselves into a corner where that is all they'll be able to have unless Giannis hits his head and randomly decides to abandon the Bucks and move to Dallas for some reason. Also Donnie Nelson is a product of nepotism who won a championship (good) by building around Dirk (good) by overpaying free agents (bad) and dumping draft assets like a guy giving out candy for trick-or-treat (horrible) and generally sucked at developing young assets when he's had them (very very bad).
Situation wise, it's probably a wash. If Zinger stays healthy, the Mavs are dangerous. If he becomes a huge contract taking up space while on the injury report, the Mavs are a homeless man's version of the pre-Miami-move Lebron Cavs. Even if you're looking at Fox and Bagley through cynical eyes, the Kings somehow someway still have all their picks going forward (for the first time in forever) and a relatively tenable salary cap situation going forward, which has to count for something.
