I was thinking the opposite (only because I dont buy the story that Aldridge initiated the conversation). Knowing what we know now I believe it was always the plan to go after a big free agent this summer, hence the initial lower offer to Wade. Riley wasn't trying to get in the room with Durant in 2016, he was trying to get in the room with an Aldridge caliber player this summer.
I disagree. plus Woj and some others have said that it was LMA that reached out to the Heat, hence Riley flying over to LA to see him. I think Riley believes Bosh/Whiteside frontcourt is set for the future. Aldridge isn't some huge upgrade over Bosh. he has a slightly more varied offense, but isn't the 3 point shooter Bosh is and def isn't Bosh's caliber in pick and roll defense. and it wouldn't make sense to replace Whiteside with him. he doesn't want to play center and isn't the rebounder or rim protector Whiteside is.
