The Steelers seem to have a special relationship with the NFL. The back and forth between the NFL and Harrison, Clay Matthews, Julius Peppers and Mike Neal has been going on for quite some time over the national publication of an Al-Jazeera report that contained now-recanted statements linking those players, along with now-retired Peyton Manning, to PEDs.
The league has been vocal about their intentions on interviewing these players and had gone so far as to make public letters they’ve sent to the players at the end of June that detailed their plan to interview these players, specifically schedule the interviews when the players were scheduled to arrive at training camp.
