Was Davis really a former Titan?

The only comment I have on this story is- he never played one play in an NFL game. He never suited up for an NFL game. He went to training camp and was cut. Does going to training camp and not making the team make you a former NFL player? If I had went to say the Pittsburgh Steelers training camp, didn’t make the team, could I call myself a former Pittsburgh Steeler?I don’t think so I know a couple guys who played college ball- were invited to camps, never made it. They do not call themselves former NFL players.. This  man wasn’t a former Titan. He never played for the Titans. I could care less about his sexuality. That is his business.
