To sum up the last several days:
(1) The NFL is investigating deflated balls. The NFL has confirmed this.
(2) The NFL has confirmed nothing else, other than (1)
(3) It was initially reported that DQwell Jackson (who intercepted Brady) handed the ball over to the equipment guy because the ball felt flat. This turned out to be a false report. DQwell now says he noticed nothing odd about the ball he intercepted, but did notice the referees swapping out Pats balls for Colts balls.
(4) There was a leaked report that 11 of 12 patriots balls were deflated, by as much as 2 psi. It is not clear if all were 2 psi below the 12.5 psi minimum, or some, or one. Keeping (3) in mind, it is also not clear that any of these balls were ever used in the game. The NFL hasn't confirmed this in any case.
(5) During a press conference, BB denies knowing anything.
(6) During a press conference, TB denies knowing anything.
(7) TB says he has yet to be contacted by the NFL.
(

The NFL did say early on (Monday or so) that they hoped to wrap up in a few days.
(9) There has been a ton of innuendo and speculation by the popular press.
I think that about sums it up.
