If I Was La'el Collins...

I'd be happy no team drafted me, or offered me an undrafted free agent contract. It makes is easy to sue the NFL for anti-trust and/or RICO violations opening the possibility of triple damages. (Note: the NFL has lost anti-trust lawsuits in the past, most applicable to Collins the suit by the USFL)

The NFL as an entity is a collection of 32 separate businesses cooperating for mutual economic benefit that includes preventing competition. Thus, the NFL is an extension of all 32 franchises, and any information shared by the NFL with more than one franchise opens them to charges of collusion. Thus, if the NFL investigated me, and shared the results of the information with the franchises, and that information resulted in economic damage to me, then there is a good case to be made they colluded and damaged me.

I think it would be easy to prove that NFL made inquiries to the Baton Rouge Police Department, and that it shared that information with the various franchises. If I can show that the NFL shared concerns over the public relations aspect of drafting me, or offering me an undrafted free agent contract, before someone else is arrested for the murder or I am cleared, then I think the case is won. And I think in light of the Aaron Hernandez, Ray Rice, Gregg Hardy and other cases involving player violence that have embarrassed the NFL there is an almost certainty that the NFL and franchises have communicated on how to deal with existing, and prospective, cases involving players accused of violent crimes.
