Attributing all of the repercussions from Kaepernick's initial protest, or even most of them, to some preplanned strategy is like blaming the butterfly that flapped its wings in the Andes for the flooding in Houston this summer. It may have contributed but not very much and you can bet the butterfly didn't flap its wings with the intent of causing flooding in Houston.
Kaepernick is dating an attractive woman, who is radio talk show host and a liberal activist, and has been for a long time. I don't know why people want to say he planned it, when history is replete with men that have engaged in foolish/stupid behavior, all in the hopes of impressing some woman or getting some.
Once he did it, it assumed a life of its own. He then foolishly selected it as "the hill he wanted to die on" and the NFL owners and fans gladly accommodated him. It should be the end of the story, but other people with bigger agendas and bigger brains than Kaepernick have all decided to make the idiot a martyr for their cause. Having already "died on the hill", he has accepted. Yet another bad decision, but at least he is getting some, which is what this was all about in the first place.
The man that would make those decisions is not cerebral enough to have planned this. It is simply another case of a man letting his little head do his thinking for him. I am not excusing him, he just isn't that deep a thinker when he fully engages both brain cells.
