Expect it, until they miss the playoffs. These stories write themselves. Rarely are there new narratives in the NFL, just recycled headlines with names and places changed from year to year.
Since the media provides so much coverage, it is not necessary to actually provide truly valuable coverage of an event like the Bills/Pats* game because there are hundreds of games per year. The article could actually say, "Blah blah blah, NFL, blah blah blah, Bill Beliache, blah blah blah, Marcia Brady, blah blah blah, Rex, Rob, Tyrod, Shady, blah blah blah." and almost no one would actually notice.
That is why the National Anthem thing is such a big deal to the media. It truly is new news. With that said, the media saturation will quickly result in a whiplash of resentment from the consumers who grow bored. Kaepernick would get more bang for his buck if he stopped protesting the anthem and moved onto another creative method of gaining attention for his cause.
