The NFL docuseries “Hard Knocks” goes behind-the-scenes of the NFL’s pre-season. This year it also goes behind-the-scenes of python hunting in Florida, as Buffalo Bills defensive end A.J.

How do you know the NFL season is almost back? The start of HBO's Hard Knocks is the first tease of the start of a new season.

In a really nice twist, there is plenty of discussion on veteran cornerback Tre'Davious White, who returned to the Bills this offseason. He has long been a fan favorite in Buffalo for years, but in a slight spoiler, White is portrayed very well in Episode 1. It's hard not to like him, as expected.
