I might be wrong (I don't follow gymnastics nearly as closely as I follow figure skating), but I don't think anyone has ever said anything blatantly negative about Mihai Brestyan, Aly Raisman's coach.
I suspect that, like a lot of gymnastics coaches, he was negligent at best when it came to Aly's eating. In an interview this past week, Aly said that, at one point, on a flight to a competition, she was so hungry that she ate a power bar, but she was so aware of how much coaches frowned on eating that she ate it in secret in the airplane bathroom. Even if that was a reference to the Karolyis, it's hard to believe that Brestyan wasn't aware of how little Aly was eating.
Aly says that, when she had some medical tests done, her body fat was so low that the doctor was very alarmed and told her that he had never seen an athlete with such low body fat. She asked him to tell her it would be fine, but he wouldn't. He made it clear that it was very dangerous. She says that there have been some long-term consequences for her health. She can't work out or she gets migraines and gets incredibly tired. In the last few years, she has had to be hospitalized a couple of times with stroke-like symptoms. She couldn't remember her name or talk or even really move. I don't think she explicitly said that it was due to how she treated her body, but that was what she seemed to be implying. I supposed it's possible that her coaches were trying hard to get her to eat more. But, if I had an athlete who was that unhealthy, I would want an intervention and would not let them work out with me until they started eating better and were healthier.
I think Simone’s long term success has more to do with her and her family than any environmental factors. She strikes me as someone who would not tolerate bad coach behavior. Given that she was clearly a star as a junior, if a coach even tried to us abusive methods, they’d have to walk it back pretty quick as she would be likely to speak out and switch gyms easily. I think Simone and her mom have done more for the “no bullsh!t” movement than any people other than Denhollander.
The podcast interview that Simone did with Alex Cooper gives some pretty good insight into Simone's relationship with the Landis. I don't think Simone calls all of the shots, though I doubt her mother would have put up with anything abusive. When Simone originally told the Landis that she wanted to go to the Paris Olympics, she was very surprised when they said no. They thought she had a history of putting too many expectations on herself. They wanted her to take things slowly, get back in the gym, start addressing her twisties, and take things one step at a time and then eventually make a decision about Paris. OTOH, when she first started visiting the gym to see the girls after Tokyo, Laurent would try to get her to workout and not just play around on the tramp.
Simone said she couldn't even look at Laurent when she withdrew in Tokyo because she felt like she had failed him and let him down. She said Laurent tries not to let anything get to him, but she knew this would get to him. (Sadly, Simone still seems to feel like she let a lot of people down in Tokyo, and I don't get the sense that she is as confident as some might think.) She doesn't say anything negative about how the Landis treated her in Tokyo. In fact, she says that Cecile helped her a lot after she withdrew.
Just before Alex interviewed Simone, Alex met Laurent and watched him working with Simone in the gym. Alex (who was a college athlete) said that it seemed like Laurent has a very high standard for her in the best way and that he is fierce and loyal in a good way.
