Rudolph's denial seems too absolute to be believable. Someone should ask him what he actually said to Garrett. He was talking an awful lot of trash. Sure, he'll deny saying the N-word, but will he own up to the other stuff he was saying? My guess is that he will deny that too.
If he had said something like, "Myles seems sincere in his belief that I used the N-word, and I know that is not what I said. I'm trying to remember if anything I said could have been mistaken for that, and I really can't. I'd like to meet with Myles and see if we can resolve this, because I don't think he believes he's lying. I just know I didn't say it", I might have given him the benefit of a doubt.
But that's not what he did. He doubled down and said he has never used any kind of racial slur. Did he grow up in a plastic bubble? It's like someone who says they have never lied. People do all kinds of stupid stuff when they are young or drunk or insecure or just angry. Lying and racial slurs are right at the top of the list of stupid stuff people do. Rudolph's absolute denial seems more designed to prop up his image than to get to the truth. Unless he's willing to own up to everything else he said during the incident, I have no reason to believe that he didn't say the N-word.
