Didn't that money go to cancer research?  That's still a good cause, cheater or not.  Unless Armstrong was lining his pockets with those wristband funds, I don't see a problem.  
I'm no NFL GM so that kid's character is none of my concern.  Character traits as a concern for the NFL is so bullshit anyway.

We're such babies.
