As a European which got to the NBA a few months ago i simply don't understand why people critize some players to change team for exemple i am mainly watching soccer and there for exemple no one critizies Ronaldo for changing his team multiple times during his career (Sporting Lisbon (very young), Manchaster United,Real Madrid, Juventus Turin , Manchaster United, Al Nassr (after his prime)) so even if you don't count Sporting and Al Nassr he changed his team as many times as Lebron who is very critiziezd for 'forming super teams' and in fact in soccer sometimes are players praised for changing teams to proof they can win with multiple teams not just with one super team only time when players are critizized for changing teams is when they join the rival team or when they are promising they plan to stay in their team but in the end they leave as free agents
So why there are so diffrent opinions on changing teams in soccer compered to Basketball?
(Sorry for my grammar)
