It may not be a coincidence that Barrett Robbins was shot several times. It may not be a coincidence that Bill Romanoski failed a physical, and it may not be a coincidence that Dana Stubblefield is injured, and also failed a physical. The other player Chris Cooper, of the 3 who tested positive of THG was a no name rookie so I guess politically its possible that it doesn't really matter if he plays...
There are coaches and trainers supplying players with illegal drugs. Not to mention the Vegas/gambling/Mafia connection. With Jose Canseco, it may not be a coincidence that he may be going to prison soon after around 15 years of solid steroid use, right after he comes out and speaks publicly about steroid use in a book.
Examples of what is happening to these people may be the reason why you hear SO VERY FEW athletes come out and admit that everyone is using something.
Then again maybe they are all clean...NOT
