I don't think I've ever seen this during a neck injury concern...What does this say about those fans? I know that this doesn't reflect all 49ers fans, but clearly a sizable number that attended the game. As fans... when it comes to division rivalries we can get very close to that line of wanting to see blood and injuries to the opposition, and as rabid and zealous a fan base as we are up here in the PNW, I would like to think that if that was Kapernick down on the ground in our stadium we would show respect to the situation.
Something to think about, as my instant reaction to this is the same disgust and embarrassment expressed by the 49ers players on twitter following the game about their fans. How important it is to never cross that line and end up losing the respect for your city and the team that plays there.
Would we be different? I hope so.
