There's virtually no way the Miami Heat would be able to acquire Giannis Antetokounmpo without including Nikola Jovic and Kel'el Ware in their trade offer. Despite the high price, it's certainly a sacrifice the team should be willing to make.
In fact, there should be really no doubts or hesitation to make such a move.
Jovic and Ware have the potential to be very good players down the line, but their ceiling doesn't even come close to the player that Giannis is at the height of his powers. While trading these two promising young players (even though Jovic finds himself in a slump to start the season) would hurt, you do this deal 10 out of 10 times for Giannis.
