Boyd is a 28-year old starter with not much of a track record. He is smack dab in the middle of his prime. Aside from starting red hot, his last 6 starts have been horrendous. I am not sure his value could get much higher if you don't trade him. His value could tank (ala 2019 Castellanos). Look at Fulmer. Avilla wanted too much for him, when he could have done a a deal last year. Castellanos' peak value was last year. Now, in his walk year, his value probably couldn't be much lower. Who wants a Okay bat, not elite, and no defense player? He is slightly better the the average AL DH (average AL DH OPS = .782, Miggy is .784 OPS as DH).
Now, back to Boyd. We are not talking about a 23-year old with 3 more years of control entering his peak years. We have a 28-year old, who would be out of his peak years. Players have "outliers" in their careers. Darin Erstad's .355 BAVG to name one. Who's to say that 2019 isn't Boyd's outlier? If a team wants to give you players, great. But asking for Torres in just plain stupid. He is primarily a SS and switched back to 2B when Gregorius returned. He is huge for a premium position.
