Sure, I can agree with that, but it's not really a "right to play" situation. They're talking about doing their own investigation, and punishing players according to that. What if the actual court system has a completely opposite ruling on the situation.
NFL suggests evidence finds Joe Blow guilty of "X," and punishes Joe Blow. Courts say evidence supports innocence... What now?
Same thing that happens with every employee of every company....your company can fire or suspend you for violation for violation of any company policy. They do not need a legal guilty verdict to do so.
Given the long suspension after the nfl finally getting/reviewing the evidence they were looking for, assuming that the evidence might have actually been strong is NOT a reach.....well not for someone having more than 2 firing synapses.
