You're right, I didn't word that correctly, some of the occasions were up to twenty years ago. Even agreeing on your arbitrary 5-10 year time line it would be absurd to think that Newcastle are unique in having the only players to have been involved with illegal substances, and the only players making racial comments in that span of time. Hell, this past weekend the Telegraph ran a story involving two Roosters players and a member of the coaching staff in the abuse and sale of prescription medication. It's probably a nothing story, just like your post singling the Knights out for these issues is a nothing post when these issues are merely a drop in ocean of similar issues that occur every weekend reported, or unreported.
You're not defending Brian Smith, that's great, I'm not attacking him. My point was how moronic the last sentence of your original post was. Smith signed two of the players that contributed to the largest of the scandals you're referring to.
