It's not for Arthur's two opponents, it's for the portion of the viewing audience who don't like his methods, just like Herm's quote was for the reporters and not his players. Obviously they're all trying to win the game, but not every Cletus and Josephine understands there's more than one way to do it.
My problem with this whole line of reasoning is that I'm not seeing anything that actually says Cletus and Josephine are having a hard time with any of this. The snowballing viral story is that Arthur Chu is annoying viewers with his unusual tactics. But I'm not seeing any actual complaints. Anywhere. All I'm seeing are stories that SAY people don't like it.
Yes, the show is seen by millions of people, and there are bound to be folks who see something out of the ordinary and have a problem. Elsewhere, I have seen the race card played, and again, in a pool of millions, yes, there are going to be people who don't like him because he looks funny. In both cases, I'm just saying that the number of people who actually have a problem is insignificant and wildly disproportionate to the uproar.
EDIT to say that of course there are the typical internet rowdies who complain about everything. My point is that Mr. and Mrs. America just don't think this is a big deal.
