SI's complete coverage of the investigation into the New England Patriots for deflating footballs used in the AFC Championship Game.
After handing down a debilitating set of penalties to the Patriots and quarterback Tom Brady for their roles in the Deflategate infractions, it's the NFL's turn to go on the defensive. Tom Brady and the NFLPA filed an appeal of Brady's decision, citing the NFL's "history of inconsistency and arbitrary decisions in disciplinary matters," and team owner Robert Kraft was vocal in proclaiming Brady and his staff's innocence before accepting the Patriots' penalties at the league's owners meetings on Tuesday. (Brady's appeal of his suspension will go forward, as the NFLPA seeks to set a precedent for future discipline rulings.) As all sides lay out their cases and the debate over how much of an advantage underinflated footballs can possibly provide grinds on, keep track of every angle from SI.com's coverage of the Deflategate saga below.
