The Braves bought out four FA years. Betts has been a 42 WAR player over six years. Let’s just say Acuna becomes one of three best players in baseball and averages 7 WAR over the next five years (so 35 WAR) and his best season would be 2024 (when he was scheduled to become a FA)
Betts just got $365M. Acuna will get $123M over the next nine years (including this one) and it is a 10/$124M contract. Acuna would have gone into his age 27 season as a FA. Now Acuna is scheduled to go into his age 31 season as a FA. Let’s say he is really good, and he gets an 8 year/$160M contract (and that is aggressive at 31 years old). So that’s $284M.
He would have had four arbitration years. Considering how aggressive arbitration is becoming, I’d say he would estimate to make $65M (Betts was scheduled to make $27M this year).
Assuming COVID goes away and with the new postseason money and general inflation (and Trout/Mahomes crossing the $400M) mark, I don’t think it’s crazy to suggest Acuna could get (being so young) 12 years/$400M.
You take his $400M and his arb years...
Acuna potential deal: $465M
Acuna current deal plus estimate $160M: $284M
