Buffalo "announced" that Williams would be moving from safety to wide receiver in 2016 and put a lot of time and effort into the joke. First, the team published an article with quotes from Williams.
“The coaches and I talked about this idea late last season after I took reps at receiver on scout team,” Williams told Buffalobills.com. “After some thought I really think I can help us win as a wideout. At the end of the day that’s what it’s all about.”
Williams and the team also shared footage of Williams running routes on social media.
Other teammates took part in the joke as well.
Eventually, the Bills and Williams let the fans in on the joke.
Although the overwhelming majority of people realized that the Williams story was an April Fools' Day joke, there were some people on social media who believed the story.
