Rowdy Gaines (swimming coverage) was not at all shy about expressing his disdain (during both prelims and semi-finals coverage) for the Russian woman swimmer, a breaststroker, who was initially banned, appealed, and won her appeal the day before her first event began.
She has been caught and previously suspended for drug violations TWICE before. He was livid (or as livid as a broadcaster can be).
Pretty sure the 100 breast final is tonight, and a young American, who also was outspoken about her chief rival after her semi-final swim, will be right next to the Russian in the final. Cheering hard for her.
