If Ryu comes back and is full value 2020 Ryu and Manoah is just meh, does Manoah stay in the rotation?
If Ryu comes back and shits the bed, while Manoah concurrently shits the bed, what's the plan? Does Atkins pull the trigger on a #4/5 at the deadline? What other choice would he have?
Best case scenario, both Manoah and Ryu pitch well and we run with a six man rotation.
