I’m not sure you can read too much into a refusal to comment. Emily has been supportive of Hubbard. Although she can obviously only speak for herself so perhaps the other contestants feel differently. And perhaps Emily would feel differently if Hubbard had prevented her from getting to the olympics in the first place.
That was a very lukewarm and carefully worded statement. Emily is an experienced athlete, she'll know that by the time she's 43 she won't be competative against women in their late teens or early 20's, she'll know her best competative days are well behind her. She'll know how impossible it would be for a woman to take a 15 year career break and come back as a weight lifter in her late 30's and sky rocket to becoming one of the best in the country. She'll also know how much hate women get for pointing out the bleeding obvious.
Her sillence when being asked the same question after she's won her medal says everything.
