No team drafted him based on the language in the CBA.
IF a team drafted him, he had the option of sitting out, not signing and re-entering the next season's draft.
IF no team drafts him, he becomes a UDFA and my NOT re-enter the next season's draft.
So, by drafting him on day 3 based on the info at hand, teams had to believe that he would waste the pick, forego this draft and sit out.
By NOT being drafted, he has no choice.
A couple of things:
If the Commish said anything about whether to draft or not draft a player who is eligible, that would be an issue under the CBA and likely grounds for a very large lawsuit that Collins would win. There's no reason to create such a lawsuit to find out, but if anything got leaked...that would be bad for the Commish.
If the teams colluded to not draft him to ensure that he could not re-enter the draft, that collusion would be criminal and would be an anti-trust violation. Again, hard to prove and would require something to be leaked, but that would be bad and Collins would win.
I don't think EITHER happened. I think each team realized the obvious which was this: His agent said so. His agent said: Draft him and he's sitting out a year. And I don't think the Commish had to say anything about a player's draft status because if the Cowboys were willing to sign Greg Hardy and then they drafted Randy Gregory, you can bet that a team would have drafted Collins if they thought he would sign ON THE CHANCE he was innocent. The issue wasn't PR or innocence. The issue was that he said he wouldn't sign and teams wouldn't take THAT chance. They'll take a chance on murderers, rapists, thieves, batterers, etc, but they won't take a chance on wasting a draft pick. Priorities. C'mon...
It wasn't until AFTER the 3rd day that he said he'd sign and by then, all the UDFA money was gone. Heck, that money goes faster every year. Pretty sure it's gone within the first few minutes of UDFA now with all the competition.
That said, now that it looks like he may be cleared, I expect that there will be a land rush for Collins. Granted, he may not be cleared for a week, but he passed the poly and he answered all the police's questions.
