I predict that league legal whore Ted Wells will come back with a report full of lots of smoke but little or no fire.
To wit: instead of pointing fingers of blame, he will conclude that the "extensive" investigation proved inconclusive and then as if to validate his BS, make a host of needless recommendations for the league to adopt regarding ball security. Just like he's being paid to do.
On the basis of inconclusive findings, Goodell will apologize to his butt buddy Kraft due to the absense of "definitive" findings, and then true to form, in reciprocity, Kraft will seed Goodell's "retirement" fund with a few million more through about 5 untraceable intermediate offshore transfers.
