Two separate issues:
Regarding Kraft, for me it's a matter of "BP" and "AP." What he says "Before Penalties" are announced is one thing; it's perfectly possible and even smart that he would be saying one thing in public and be playing hardball behind the scenes. What counts is what he says and does "After Penalties" are announced. He is probably limited by his ownership agreement as to any legal action that he can take, but there is a wide range of what he might be able to do beyond that, ranging from empty rhetoric to supporting an appeal or lawsuit by Brady to much more. I'm giving him the benefit of the doubt until we get to that point...but only until we get to that point.
Regarding Brady, it's just speculation until we know what penalties are announced. But, he and Gisele have very deep pockets and can afford to go toe-to-toe with the NFL, supported by the best legal minds in the country, even if Kraft doesn't chip in. Saying anything more than that is pure speculation at this point.
What is not idle speculation, is that this could get very, very ugly, either in terms of the Appeals and Discovery process that Brady might initiate against the League, or, worse, in terms of what Brady might do if he feels that Kraft isn't supporting him adequately. I have a feeling that some tough negotiating is going on this weekend.
