Look, other argument aside, that's eventually might not be their choice to make. If Kawhi wants to be traded, you have to move him to at least get something for him. LMA might not want to stick around long term if we can't replace him with some decent pieces and/or another star.
Look at Miami, going from the top of the league to the bottom in a whim, same with Cleveland going up, down, up, and now again with a big cloud. This is a player's league, and the pool of actual franchise guys is limited.
