Everything I've read suggest Kaep was not given a standard waiver form, it was much shorter. I don't think the NFL had any intention of following through with Kaep in the NFL. This was a PR stunt by the NFL.
I also don't think Kaep thought this was a legit shot, so perhaps he flipped the script. He did this on his terms, like it or not. Maybe he planned this from the beginning?
And I'm also of the opinion, the NFL is scared of Kaep. Kinda funny if you think about it, a massive corporation scared of a single guy who spoke his mind and got his peers engaged. That's some power.
I don't think he really understood how kneeling would have been received by society. I wonder if he'd change things knowing what he knows now about kneeling and what a lighting rod it was.
Ironically, it doesn't seem like he's controlled the narrative in any of this. Kneeling was probably the biggest mistake in all of this, as it seemed to have really turned people off to the NFL in general.
