There is no guarantee JDL comes up and effectively gets big league hitters out as a starter. If you move him to the pen you've just replaced Osuna.
The gain for this year seems so minimal to me that it's not worth it. Would JDL+Sanchez even be > Sanchez+Osuna ROS? Probably not.
In December sure. You don't do it in the middle of a pennant race though. Once again these guys aren't computer simulations.
You've also assumed another addition and the call-up of Barnes. Not so fast, Cyborg!
I hope you're confusing me with somebody. I hope I never told anyone to commit suicide, and if I did I apologize and have grown up since then.
It was really a joke Robert. I'll be sure to leave you alone from now on.
