Everyone is forgetting Adrian Peterson is still in court. The NFL is going to appeal that all the way too, but odds are Peterson will win every time. The one thing that makes the Supreme Court take cases is when two courts rule the exact opposite on what is essentially the same case.
And believe me, all these labor unions all across the county are salivating for the supreme court to knock the crap out of the NFL. It will take years, but I would be shocked if this does not end in the supreme court simply because of that fact.
It is politics. Kraft is the literal reason Goodell has his job. Kraft cannot start unilaterally openly campaigning for him to get fired without looking horrific and losing a lot of credibility and power in the NFL. Kraft now knows he has totally mismanaged this situation and needs to dig himself out, but it is not something he can do overnight, it is going to take a few years and it needs to be directed subtly. Kraft really loves the power he has in the NFL, and he really desperately wants to be a mover and a shaker. He thought he had that with Goodell, but obviously Goodell screwed him over. He has to fight a war by proxies so he can handle the next negotiations for whatever is coming up and fix this mess himself.
