I'm admittedly not an NBA expert, but it never seemed like a difficult decision to me. Wiggins has never shown any indication that he'd ever be the kind of player you'd miss. On the contrary, he's consistently ranked among the worst regulars in the league, according to the advanced metrics. Some people see crazy athleticism, and seem desperate to extrapolate that out to something more than it is. This team will be a lot better off without Wiggins, and not just because of the salary. He's a negative value player.
