In this case this is true as the agent is making a huge deal about this but it should be private the way it is when an agent has multiple NBA, NFL, MLB, players.
This agent guy has pretty much likely excommunicated himself from future deals.
Perhaps that would happen with some but I look at it the same way as having a job. I don’t go asking nor do I go disclosing what my salary is at my job or asking orders to divulge that info.
It’s no one’s business.
