The thing with both of these young men is their lives are in danger if they continue to misuse drugs. Eventually that will catch up with you physically and even an athlete in prime condition cannot be immune to the physical toll on one's body.
I heard a drug counselor on the radio today that said if one is "addicted" to pot the odds are eventually he/she will go onto other "hard" drugs. That may be the next step for Williams if he's not there already.
I think they both need to have counseling, professional rehab care and get their lives in order before they ever again worry about football. Their lives are far more valuable than the Cowboys or Dolphins ever could be.
I am a bit confused by the Carter situation because he denies the cocaine charge. Denial I guess.
