He said "it's not the case that I will always be able to re sign Garrett to the minimum salary via 9.6. If his card for 2020 exceeds that minimum salary of $3M I won't be able to get him for $3M in 2021" but I thought once we set the price for 2020 that the SOM price was irrelevant...it's what our salary structure says.
You are correct. You can re-sign Garrett again via rule 9.6, but at the higher minimum salary of $3 mil for an arb 2 player. In doing so, you forfeit the right to sign him to a four year extension at the 50% price. You would have to extend him the following year at the 25% price as he would be in his arb 3 year. This is why I chose to extend Berrios in 2020 rather than resign him for one year at a lower price.
Doug is right about the logic of the rule. During a players arbitration years you have a choice of renewing the player at the escalating league minimum price without going to arbitration. Take, for example , the likely contract trajectory of Wander Franco once he is promoted:
Year 1 (pre-arb): sign for $500,000
Year 2 (pre-arb): re-sign for $600,000
Year 3 (pre-arb): re-sign for $700,000
Year 4 (arb 1): re-sign for $2,000,000, go to arb and pay no less than $2 mil, or extend for 4 years at avg of top 50% ss
Year 5 (arb 2): re-sign for $3,000,000, go to arb and pay no less than $3 mil, or extend for 4 years at avg of top 50% ss
Year 6 (arb 3): re-sign for $4,000,000, go to arb and pay no less than $4 mil, or sign contract extension for 20 years (I jest) at avg salary of top 25% of ss. If you don't sign a contract extension then he becomes a free agent.
This scenario makes clear why the arbitration rule doesn't work, and why an owner might wait until the arb 3 year to sign a contract extension even if it costs more. You are paying for control.
