They are supporting pain and suffering.
The NFL, like most of mass media, has such a sway over the populous, and they took a strong stance on this issue in my opinion. I am glad that they continue to not back down, even if they are using a "uniform violation" as the reasoning behind it.
Now they just need to switch to synthetic balls.
My message to those 5 players...
...you want to support Vick? Never let him forget the pain and suffering he caused to the dogs. Don't let this kind of abuse happen again. Fight animal cruelty.
