What's up with Ricky Williams?

Seriously, can anyone figure out Ricky Williams?

Williams, the erstwhile Heisman Trophy winner and apparent proponent of pot, failed another drug test Friday, meaning his return to the NFL is delayed -- again.

After being banned from the NFL for last season, Williams went to play in the Canadian Football League and had a decent season. Williams long has had issues with the media and seems to want to live an out-of-the-box lifestyle away from the field.

That's OK as long as you don't turn your back on your teammates or people who have invested millions of dollars in you. Williams needs to make up his mind once and for all whether he wants to play the game or not.

If he does, good for him. If he doesn't, eh, good riddance.
