He stood in a snowstorm this past winter outside Ralph Wilson Stadium holding a sign that read, "Nobody wants it more than me."
"I stood out there for two hours until the cops came," Knox recently told Fansided.com. "I had frost all over my face, my arms were beet red and I was frozen, but I didn’t care because I wanted [team president] Russ Brandon to see, I wanted [coach] Rex [Ryan] to see, I wanted [general manager] Doug Whaley to see, I wanted every single coach who came in that day to see that nobody in or out of that team wants it more than me and I know I got my message across."
Knox is a Buffalo native and attended the University at Buffalo, last playing in 2011. He didn't get a shot in the NFL until Dec. 30, 2014, when the Bills signed him a future contract. He was released May 13, 2015, when the Bills signed ex-Jets fullback John Conner, a favorite of Ryan.
Despite Knox's insistence that he "got his message across" to the Bills' coaches and front offices, he has yet to re-sign with the Bills or get a shot anywhere else.
"I’ve thought a million times about it, if I ever get the chance to see Rex in public and what I would say to him," he said. "If I could get in front of NFL GMs and say a couple of lines about what I think I can bring, it would be that I don’t think anyone wants it more than me.
"I would die for it. I am not afraid to die for it. I’m not afraid to give it everything I have. I don’t care about money. If I cared about money I would have stopped chasing this dream a long time ago and just started working."
