I don’t doubt he could start and be a decent back end option. I question his ability to stay healthy and wonder if its worth streching him out to be a decent 4th or 5th when he can be a dominant reliever right now. The worst fear would be streching him out and he blows his elbow out and we lose him for 12-18 months again. The rotation spot he wants isn’t currently available and will only get more jammed up over time. Hes a reliever now and a good one.
