The Dolphins will be fine, Ronnie Brown was going to be the starting RB anyway.
Yeah but we loved having Williams as a back-up, especially at the league minimum salary.
If Williams does get suspended, it will cost him his entire salary for the year, and if he gets another chance, it will be at a far lower salary. Basically he's proven you can't count on him being there, so you can't pay him like a front line running back.
One thing about Williams, though, unlike many players busted for fighting, assault, etc., he just self-destructs.
