Chances are Medlen wasn't hurt by his rehab but hurt by switching to a starter so soon after TJ.
Agree with this. When a guy is a RP, you switch him to starter and he blows out his elbow, you make him a RP again. THAT'S what I blame the Braves for - the aggressive approach to usage, if not timing. I feel like the right thing to do, as a franchise, is to take the most conservative approach with your players in these major injuries. If that means role/inning/pitch limits, fine. Don't be part of the problem.
That's not to say Strasburg or Zimmermann or anyone else can't blow out their elbow again anyways. But you just look like a bad franchise if it appears you may have contributed to ruining a guy's career by asking him to do more/faster than maybe he was capable of. Maybe Kerry Wood and Mark Prior were doomed anyways, but Dusty Baker still looks like a jerk.
And you never know what kind of benefits you reap from being the "good guys" but I certainly believe in karma (or at least the power of reputation!). What if the only reason Giolito signed a bottom half of the first round deal (when he could have gone to college) was that he felt comfortable with the Nationals handling of pitchers who needed TJ? And what if Giolito ends up a top-10 SP? What if agents start seeing the trend of Braves pitchers with repeat arm issues and start advising their clients elsewhere? You never know.
