In a lot of areas of this League, three owners control everything - Kraft, Mara, and Jones (and Jerrah seems to vote lock step and barrel behind Kraft on everything). They are the power brokers in the league.
There may be 31 other teams that hate Belichick, but every owner loves Kraft. Kraft has made them tons of money. He is on the TV committee and has been directly responsible for a lot of the TV deals. He also was the major force in getting the CBA done a few years back. What he says, most of the owners fall in line behind him.
And Goodell owes him. Goodell would not be in the position he is in without Kraft. When they were voting on a new Commissioner when Tagliabue stepped down, the vote was split and it was Kraft and Mara who threw their support behind Goodell and convinced all the owners that it was in the best interest to vote Goodell in unanimously.
There are two owners that Goodell cannot completely alienate or he is done. One is John Mara. The other is Bob Kraft. Kraft will do what is best for the league to a point and that is why the Pats fell on their swords in Spygate. He won't fall on his sword this time and he is going to demand that if Kensil and/or Grigson ran a sting on him and smeared him and his franchise in the media that there will be heads that roll.
With all that has come out already, the Wells report will have to show the League in a negative light. And there will have to be a fall guy. It looks like Kensil will be that guy. With the fact that we found out they let a guy they knew was stealing balls handle game balls, the fact Grigson told the league prior to the game he suspected the Pats were deflating balls, the fact that someone in the league is leaking slanted stories trying to smear the Pats., etc.; someone has got to take the blame for that. Kraft will demand it. Both Kraft and Goodell have implied that someone in the League will.
