Speaking of Embiid though, have you noticed that he is getting booed by the fans whenever he touches the ball? Not sure way he is beating boo'ed or what, most probably they think that he didn't go and represent his country Cameroon in basketball?
Embiid also has French citizenship. So, it's no surprise that fans at the Olympics in France booed him a bit for his decision to play for the US team instead of the French team. In principle, Embiid's decision is quite understandable because he wants to win the Olympics, and it's obvious that he can only do it with the US team, not with the French team.
We don't really know what's the reason behind as he's a US citizen as well just like you said might be choosing the easier path playing with the US another version of a dream team, but also he might considering his career though we really don't know what's behind that decision it's his personal and possible that he and his camp deal about before deciding.
In terms of playing with Wemby, Gobert and him, imagine if they are all playing together Wemby play as PG he will design the play and execute either giving it to Embiid or a kick out for those shooters.
