He is definitely not better than Josh this year - Riley I get concerned about only because he always struggles early on and then adjusts. Moving forward Riley is better than either of them.
However, it still gets back to the question and it is so easy in hindsight to say but what is the better pairing?
Brantley 16
Ottavino 9
or
Donaldson 23
Neck 4
Comp pick or addition year of Donaldson
Who knows if Brantley or Ottavino ever wanted to come here or if they would have signed at those rates. Its also easy to say the long term nature of the contracts are more palatable because of what we know now with Acuna/Ablies.
If all those things are just assumed its clear the Braves are a better team with option A.
