In this scenario the raptors view RJ and Scottie as the two pieces to build around as such they get guys who will stretch the floor for them and have play off experience which will help them next year.
MPJ is a much better fit next to scottie offensively then Ingram despite Ingram being viewed as potentially more talented
Moving off quickly is to allow the team to actually have flexibility in the future and get two expiring contracts which will help them in 2027 when the decision around Dick and MPJ would be made.
Getting off poetle for a shot blocking long threat who can stretch the floor will greatly help with this teams ability to actually run plays with Scottie and RJ as the ball handlers.
