Yes, KD is a monster - a real monster both inside and outside. He's unstoppable man. His outside shots, mid-range shots, isolation plays, fade away shots. All of them, he's mastered it.
I think the reason why he was hated so much is because he chose to join a team that's already very strong. 73-9 and the team that knocked them out despite leading 3-1 in the Western Conference finals. I guess that hurts a lot for a fan watching your superstar joining a team already used to winning.
I think so too... and I think in America, most fans support teams rather than players so it hurts even more. Outside the US, I would say most NBA fans support the player rather than the team.
