Deferrals are bad for the players and especially when inflation is higher. No one is signing a deferred salary deal anymore.
The Werth deal didn’t have deferrals. Also the offer to Soto did not.
Have you forgotten the Shohei contract? He just signed onto the biggest deferral in history but the Dodgers are far more able to afford the payments after the player is gone than the Nats are.
Deferrals are good for agents and some deferred contracts, including Strasburg's, include interest payments.
Werth had a deferral with interest that was negotiated while he was still under contract in 2016. We don't know the details of the Soto offer because only the headline number was made public, but Rendon and Harper absolutely were offered deferrals, with Harper's being $100 million of the $300 million total.
