Jebus! He's 17 frickin' years old. Let the M.D.s do their jobs. If they think rehab is they way to go, then let him rehab. I'm guessing he's probably at least 3-4 years away from making the big club, so why rush a kid to go under the knife? Evidently these are the same guys that handled Zimmermann and Strasburg, I reckon we might be able to trust their skills a little.
