The NFL offseason has been chugging along, and the start of the season seems right around the corner. But one important milestone has been missing, as we still don’t know which team is going to appear on ‘Hard Knocks.’ The popular HBO show has usually announced its team for the upcoming season by now, but not this year.

According to Peter King of NBC Sports, there’s a reason for the delay.

“NFL Films—which drives the bus on the “Hard Knocks” process—seems to be a little bit behind in the team selection, in part because of all the programming associated with the league’s 100th season in 2019.”

The NFL is going all out to celebrate its 100th season, so this makes some sense.
