Fascinating, and complex.
So that basic ruling relates to the fact that the players themselves cannot be punished for the "pay" aspect of the pool, but the "intent" aspect. The rules pointed out that they could not participate in such a pool, as I recall. Just participating was wrong. But apparently the 'jurisdiction' for that penalty is the court, not the league. Very very odd.
If they must be punished by the league only for intent, not the rules as previously communicated, which simply said participation, then, as others have noted, how do you prove intent? Yes, I participated in the pool. Yes, that player got injured. But I did not intend to injure him, I would never do that. Sort of a 'he thought, she thought' argument.
Further, since the players are now active, do they go on the 53? Do the teams have to release players? Do they get an exemption?
All these players will have their salaries guaranteed. If Vilma, for example, gets suspended for 16 games - or maybe reduced to say 12 games, will he be suspended without pay? Presumably a suspension will over-ride the veteran guarantee, but that's one more issue to argue.
The whole 'the league can't punish for participating in a pay-to-injure pool' which was previously discussed related to this case is very complex.
If, in the end, these players are vindicated, I don't think that's a good thing for the league. Like Goodell or not, if lawyers can get involved like this and argue against suspensions for violations of the CBA, in a dangerous game like football -- not sure I really like that direction. What about steroids? Where else does this lead? Do players now routinely hire a lawyer for the next suspension?
