There was an Overwatch pro player who got sacked from his team and banned for a similar (but objectively worse) outburst. The guy basically accepted his lumps but tried to make excuses about how he just wanted to say the nastiest thing he could - "I was extremely upset and I was trying to make the person I was angry with upset as well". Now, in a twisted kinda way, that makes sense. A conscious effort to say something you KNOW will upset and anger someone - you deliberately choose the "worst" word you can think of. But I very much doubt that's what Chevy was trying to pull.
(Video below doesn't show the guy screaming the n-word btw, just talks about the incident and shows the context, apology etc.)
