The Houston Rockets acquired a former rival in Kevin Durant. Perhaps that's an understatement. Some new comments from Jabari Smith Jr. make it clear that Durant was closer to an enemy.
If you weren't there, you won't understand. Durant was already a problem as a member of the Thunder. He made life difficult enough for the Rockets. When he joined the Warriors, there was widespread outrage.
In fairness, this was an MVP candidate joining the best team in the league. Durant didn't form the first super team, but he did form the super-y-ist one. When he joined the Warriors, it took the super team trend to a new height.
