The NFL changed the way it will handle teams featured on HBO's Hard Knocks back in 2013, deciding to compel certain teams to appear on the preseason reality show. With the playoffs locked and coaching changes -- we think -- on lockdown, we know what teams are eligible.

Assuming no other changes, there are nine teams eligible for Hard Knocks in 2015 either because they did not make the playoffs in the last two years, were not on the show the last 10 years and/or do not have a first-year head coach.

The Giants, Redskins, Browns, Texans, Jaguars, Titans, Vikings, Buccaneers and Rams are all eligible to be compelled by the league to participate because they don't meet any of the three criteria.

Here's the rest of the teams are exempt from being forced to appear on the show:

Playoffs Last Two Years: Patriots, Steelers, Bengals, Ravens, Colts, Broncos, Chargers, Chiefs, Cowboys, Eagles, Packers, Lions, Panthers, Saints, Seahawks, Cardinals
