Trade doesn't work because of money however the raps are almost certainly trading siakam, vanvleet, poetl. please tell me how many picks each team would need to throw in.

DALLAS I don't want Kyrie on my team. We have Luka Doncic, one of the best players in the world when he has the ball in his hands. We do not need to pay Kyrie all the money in the world just to take the ball out of Luka's hands. So we sign and trade him and in return we get Tyrese Maxey. The perfect two man for Luka, Maxey is an amazing 3pt shooter off the ball. The 6ers offer us Harris, but we have so many fowards and not enough big man. So we deal Harris off for a taller guy who might be a bit worse, in this case Chris Boucher.

76ERS If harden stays then you have a crazy big three of Kyrie, Harden and Embiid who complement each other well enough. If harden leaves then you have practically just replaced him.

RAPS The raps could be losing/trading a bunch of guys this offseason, so you get Harris because you know he's going to score 18+ a night. You can afford to take on the contract because of your young guys' team friendly ones. Maybe you trade siakam for a younger guy or the 3rd pick. Maybe you keep siakam and trade poetl for a contending piece.

*The third team (raptors) could have really been anyone.
