oldtimer, in 2019, his last full season, Benintendi had a .774 OPS, and a 100 OPS+, meaning he was exactly average.
Do you really think it's going to be an easy matter to replace him with a player who is guaranteed to be better than that?
And what if you trade him, getting back little, and he returns to his 2018 form?
You're really not thinking through the negative possibilities here, you're just assuming the positive ones.
