Yeah, smoking weed is against that league's rules. If they get caught, they get handed legitimate suspensions. Suspending a player, or a person in any job, over merely an allegation without doing any investigation whatsoever sets a dangerous precedent.NFL players get suspended and lose millions of dollars because they smoked weed. They get cut from the league for making political statements.
Nobody is entitled to make millions of dollars playing in the NFL.
I'm curious, what kind of proof would be sufficient for you exactly? What kind of proof do you think is actually available in rape cases?
