the Raptors get two expirings and a 1st for him. they needed a back up C, and they both can fill that spot
the 76ers get Lowry for Melton. I think he can be a really good fit with Embiid and Maxey. He's perfect for this team: a solid Pg who has already led a team to a championship, local boy, experienced, winner mentality, some things the Sixers has lacked lately, and he's a expiring as well so he fit into their future plans heading to the fa. Also with this move they go under the tax
The Heat get two guards (they are lacking there) and give a future frp and Lowry's expiring contract
