If nothing else you've got to respect the set on Colin Kaepernick.  On military night or whatever they're calling it in San Diego, he took a knee during the National Anthem.

Pro Football Talk is reporting that Kaepernick was joined by a teammate, who also took a knee.  I can't find any video supporting that.  But if that's what they want to do, who cares?  It's their right.

Kaepernick was booed when he came out of the locker room and onto the field.

He was also cursed at as he made his way back to the locker room.

I'd say if he wanted to get attention then mission accomplished.  A lot of people seem to be hung up on how he did it instead of why, so I don't know that it completely worked as he intended.  But it's a start.
