Jay Glazer usually gets it right. He's very well connected in the NFL. He said expect Kaepernick to be released before the start of the season. It's not all about the national anthem. There are many who believe he is washed up as a QB. He may have done what he did to expedite his release.
If you think it will cost him an opportunity to play NFL football, forget it. NFL teams sign criminals if they think it will help them win.
