Ben Simmons
Everything went wrong for Simmons in Philadelphia as teammates and fans lost patience with him. The Australian-born star effectively went on strike as he cited mental health issues. This is never something to take lightly but the franchise didn’t have much sympathy for him. They saw him as a petulant and selfish figure.

This may be unfair but the writing was on the wall. Simmons was delighted to leave them behind and join the Nets while James Harden went in the opposite direction. He didn’t receive a warm welcome when the Sixers played Brooklyn in their next meeting. But Simmons was happy to be away from this toxic environment (via CBS Sports).
