This is really the most valid point in going after Euros/other foreign players. It's overly simplistic and lazy to make this a white/black thing. There are lots of white players who would much prefer playing somewhere other than Utah, for various reasons. On the other hand, there are no doubt African American players who end up liking the area based on different personalities/preferences in life.
It's every bit as likely to draft a foreign player who grew up a Laker fan, or has some other reason for wanting to go elsewhere in free agency. Then what, we decide to only draft local college players? Those guys might prefer another team as well.
This isn't about profiling people based on where they live or the color of their skin. It's about finding high character individuals and then building a relationship with them that you can at least get a good read on what they plan/want to do(although there are no guarantees, regardless). Even then, you always take BPA in the draft, and work out the details later.
Drafting someone like Donovan Mitchell is about as good as you can hope for, regardless of race or origin. Down to earth kid who seems genuinely grateful for his opportunities in life, as opposed to an entitled player who thinks he deserves an automatic max contract after a mediocre year, just because he's ****ing special.
At the end of the day, people are individuals, and talent and potential can't be overlooked due to race/origin. If you happen to draft someone who doesn't want to stick around, you just have to get a better feel for that, and ship them out while they have trade value.
