Ricky Williams, through his agent, has already stated his intention to apply for reinstatement to the NFL. It's not like he has a choice; Huizenga's got him by the short-n-curlies as far as contractual obligations go.
He's also undergoing continued drug testing, so I doubt he's going to suddenly be suspended out of nowhere. Besides, one more suspension and he's permanently banned from the NFL.
Ricky's a head case. He'll end up like Jefferson Street Joe Gilliam, which I think is very sad.
