Rocsons arm just looked like it's been in a cast for a few months. Either his arm was repaired properly or it wasn't, time is going to tell.
Yeah, hard to get things back to where the man upstairs created them, but modern medicine and orthopedics are amazing. I would be more so concerned about where he is mentally versus physically. I feel he'll be in top physical shape lacking only where the injury limits him, however the body can also be amazing in that it finds another way to perform with damaged components...depending of course. We shall see. I hope he can return and be competitive. The cards are stacked against him to an extent, but these guess are dead on magicians...That arm is far from being healthy. I doubt you see him in 2018 if at all.
