That it started as a tribute to veterans isn’t clear to me from what I read online.
To be honest, this year I’ve been watching more football than ever. Coincidentally, my son started playing, and my interest was revived after years of complete ambivalence. I haven’t turned the TV on in time to see any of the pre-game festivities; at this point I have no idea if anyone’s still kneeling. Don’t care much one way or the other.
Interestingly, it was a wounded veteran who suggested to Karpernick that he kneel, to symbolize both Kaepernick’s protest and to pay respect to veterans. Go figure.
