I meant that taking the chance that he blows out the elbow and needs TJS is not worth the risk. In my opinion, which is not based on MRI's or any personal medical knowledge, is that his treatment should be with his long term health/ability to contribute in mind. I fear that is not the case.
I'm getting the impression from DRS and others (DRS, feel free to correct me) that the risk is not necessarily changed whether he plays right now or not. I.e., the elbow may already be effectively blown out, in the sense that there is significant damage that will require surgery to repair, and the question is just, can the athlete perform effectively with the joint in its current state, or not? If so, then maybe it's worth going on for a while--worst case scenario is that at some point he has to shut it down.
Put another way, it doesn't make much sense to say, "OMG! We have to shut him down and do the surgery NOW, or he might end up needing SURGERY!"--unless putting the surgery off worsens the recovery time or the long-term prognosis in some way.
