WE'RE not aware of anything like that. Both brothers were All-American, but no one we know has ever heard of them being Olympic-caliber. Something to consider is TRAINING for the Olympics and then actually trying out are two VERY different things. If he TRIED OUT, likely that would be listed somewhere in his official bio dating back to his NWA Crockett years, and hyped on TV, even if he didn't make the cut. The Steiners have never come up as being on par wrestling-wise with guys like Brock, Bobby Lashley, or any other NCAA-class wrestler, so our thoughts are that they may have been good enough for All-American, they probably would not have been able to advance much further than that.
Also, we wouldn't rely on Wikipedia too much, because most of the fake Von Erich stories that The Observer and the Torch have debunked (Kerry would have made the Olympics, were it not boycotted, David died of Enteritis rather than OD on drugs, et al) are all there as factual.
