Stating that you are not interested in a free agent definitely affects the market for a free agent because it makes it fewer teams who might be bidding that we don’t know about. It is absolutely a market distortion, the most famous agent in the sport is legendary for his leverage of unknown mystery teams in the bidding process, that isn’t credible when people like Reinsdorf are allowed to flaunt the rules.
Hete is a very similar example from Aaron Judge that if it happened was absolutely tampering, just as Reinsdorf’s was.

In this context, it is absolutely undercutting his newly hired GM, who should absolutely have the authority to make player personnel decisions himself. With their cleared payroll, Getz could have had an option where he comes in with a plan to offer Ohtani $400 million and aim for 2025 when his elbow is healed and it could be a real strategy. But this owner doesn’t respect his GM enough to allow him to work, and Ng is smart enough to see that- she just quit when an owner tried to pull that crap.
