It's possible someone from the organization reached out to him and told him to delete it. I never seen a team reporter delete something because of fan's reactions.
I'm not sure why anyone would think that's possible.
If it were true, he would have taken it out of his article and he didn't do that. Not sure why anyone believes that with no evidence except that people want to believe that everything is a giant conspiracy these days.
And Nick has gone on multiple rants recently about how much of a cesspool Twitter is. I also have no idea why the organization would want that deleted. If anything, they would want to soften the blow if they were planning to hire Rizzi by starting to get people used to the idea of it and it doesn't hurt them if they don't hire Rizzi.
