Here are some of the ones I have heard. Most from a Steelers board of all places.

1) Kraft was one of the chief people involved in getting a new CBA. The league owes him this.
2) Kraft's wife passed away this year. The networks would love this story for the Super Bowl.
3) Goodell is in the back pocket of Kraft since he was responsible for him getting the commissioner job.

So, you heard it hear first when the flags start going against the Ravens.
