Some people just don't know what they're watching with Luka or the Euro league.
For example, Luka has played nonstop for quite some time, just like Bogie did last season. And that needs to be taken into account. He's looked faster and more athletic at other times. But he's a bit worn down.
Furthermore, pointing to a single game here or there because it lacks eye popping statistics is reaching. The kid has won nearly every individual award someone can win in Europe. That doesn't happen if 8/8/2 is the norm. But even if it was the norm, he obviously affects a game in ways that everyone in Europe seems to understand and those watching youtube highlights don't.
While I don't pretend to know for certain that Luka Dončić is going to develop into a star or generational player, he has the most potential to be one of those players than anyone else in the draft. While there are other good players, none of them have the all-around skillset that Luka does. Those that believe he has maxed out his potential are merely looking at it as if the glass is half empty rather than half full. Perhaps Luka is just far ahead of the curve in his personal development? But that doesn't mean he can't get a lot better than he already is. Look how much better Steph Curry and Klay Thompson got in years 3 and 4. And Steph had 3 years college experience before that.
Point is, skilled players lacking elite athleticism have high ceilings too.
Lastly, while I recognize and admit that Marvin Bagley is a nice talent and likely to be a solid, maybe great NBA player, there are similar type bigs entering the draft nearly every year. AD, KAT, Cousins, Jabari Parker, Embiid, Drummond, Julius Randle, just to name a few. I won't say these players are a dime a dozen, but they're out there. But Luka has the look of a rare talent that comes along less often.
Not saying he's gonna be on the level of LeBron James or Larry Bird, but he could be something close even if different. A guy that can pass, shoot, rebound and has such high basketball IQ that he impacts the game beyond the stat sheet and is a leader. That's not near as easy to find as a 20/10 post player (and this coming from a staunch Cousins supporter).
While it'd be nice to have a player like Bagley, I'd rather take my chances on a player that could be transcendent. When the Kings took Tyreke Evans back in 2009, they got a heckuva player. But they passed on a player that became transcendent in Curry. I don't want to see that happen to them again.
