And you are telling me in the heat of the moment the same guy who flew off of the handle and tried to hit a guy with his own helmet was acting calm, cool and rational because he thought that would help him long term (when it clearly hasn't)? Your story gets less and less plausible with every explanation.
Garrett's teammates want to take his side. If they had heard any notion from Garrett whatsoever that he though Rudolph had said that they would defend him. Instead they are not.
If anyone on the field had heard anything remotely resembling that (Rudolph would have had to said it loud for anyone to hear with the crowd noise being what it was) they would speak up for Garrett. Yet they are not.
So you have a case when everyone is saying no they didn't hear anything. You have no camera angles despite probably 100's of cameras being on him (including cell phones) that can see him saying that. You have Garrett who himself did not say this happened until today even though ALL of the evidence would say he would tell anyone willing to listen that this is what was said if that is actually what happened. Not to mention you have an entire team full of African Americans supporting Rudolph.
You should take a better look at your biases because they are showing through on this one.
