There seems to be some confusion about who exactly Luka Doncic is, and I have a theory on why. Trades tend to alter our perception of a player — whether consciously or not. I think we eventually convince ourselves that, no matter who the player is, they were traded for a reason. We know that wasn't the case with Luka Doncic. There was no reason for him to be dealt other than hubris from the Mavericks front office.
And yet... Luka being dealt mid-season, then not quite looking like himself immediately (although he finished the season on an outrageous tear) in his first short stint with the Lakers, was confirmation bias on a bias most of us weren't aware we possessed.
