I think you are overestimating what I think Aquino’s value is. At best, he’s a 4th/5th OF. A 1-2 WAR player.
He has a .650 OPS after his 2019 debut. I think that is reasonable for him to maintain. MLB history is filled with backup OF’ers with a .650 OPS and strong defense. He’s rare in that he’s providing his defensive value from RF, but I think it will be enough to make him a decent backup right fielder.
