This article sites that the USA should receive the same treatment as Russia for their "win at all costs mentality". The Russians were banned for cheating because they wanted to win- simple, to the point, and something we can all agree upon. This article is focusing on USA Gymnastics particularly (though is more than happy to throw some shots at NOP and other USA busted athletes) in regards to their repeated negligence to stop Nassar and others from allowing the abuse to go on because of a "win at all costs mentality".
I cannot say I disagree with the sentiment that there needs to be a steep penalty for the US and I would 100% support USA Gymnastics from being banned in 2020. I would stop short of banning all of the US delegation as while the US is not perfect and will continue to have athletes that are caught doping, the cover-up of abuse was seemingly limited to US Gymnastics and it should be their punishment to bare.
That being said, NBC would most likely ask for a refund of their huge TV contract as they would stand to lose millions of advertising revenue by not having US Gymnastics in prime time so I doubt this will ever happen.
