What distiguishes Angle is that he is an Olympic gold medalist which is something he certainly played up during his time in WWE. In another era he'd have been the perfect baby face. But somehow they turned some of his baby face attributed into a very heel persona. As an Olympic hero/gold medalist he was not liked by the WWE universe however he still was able to put on a good match and had a legit amateur wrestling background as he was an Olympic wrestler and that was what he got in gold medal in.
I look forward to his eventual return even if he doesn't wrestle full-time again. He deserves one more run in WWE.
