1. He's asking them for a job, not the other way around. That's like no showing a job interview and demanding they switch it to a day you like better.
2. Its absolutely clout chasing. nikka wanted his own camera crew there, for what? The only way NFL films could edit the footage to make him look bad was if he was actually out there throwing bad passes. But I'm sure it was just for transparency and not to collect footage for a documentary to be sold to a streaming service
3. What does he have to gain? He has to keep the people on his side. This is the social media age and people will forget you in a heartbeat. His former team is flourishing without him, black QBs have taken over the league, and his star was fading until his ol lady went at Jay Z.
