I honestly believe that it's at least plausible they never saw the tape.
If they did see the tape and kept it a secret, I dont think they would have cut Hunt so quickly after the tape surfaced. How would that look to the rest of the team and organization? You had an understanding with a player that youre overlooking a transgression, but then immediately cut him with it comes out? It seems like bad business especially considering the tape isn't THAT bad. Also consider that if Kansas City did have the tape in February, then they would have known it would eventually leak anyway.
Finally, idk why so many folks on here are so quick to give Hunt a pass. Dude looked a little too comfortable putting hands on a 19 year old girl
