Biles was at UPenn for a year before he blew out his knee, otherwise, he would have continued to wrestle...Plus, that's an Ivy League school, so he HAD to have great grades just to get considered to go there...I think a big difference there...

Another thing, I don't ever recall Hernandez competing on the national and/or world level...Biles won more than a couple national titles, including a cadet/junior title in greco, and he was a top 4 competitor in greco worlds...I think this pretty much speaks for itself...
