Well there are reasons for his release. For one, he is already set to serve a 4-game suspension to start the season for violating the NFL's drug policy. He also showed up to camp out of shape. And if I remember correctly, he was in and out of Rex's doghouse last year.
Sounds like your typical talented sports athlete who needs a wake up call.
So if he's facing a 4 game suspension and nobody signs him until Week 5, does he still have to serve the 4 games or does being out of the league count? I'm guessing it doesn't, but it seems like it should.
Normally I'm on the owner's side of things, but this rule seems incredibly unfair to the players. Makes it much harder for Williams to catch on with another team.
