Because of the invasive (from a team perspective) nature of Hard Knocks, whomever is chosen each season needs their back scratched, too. This is why we so often see a team that is bogged down by stagnation and irrelevance (the Buccaneers in 2017), a team that is desperate to say no really, everything is OK now, we’re not a nightmare circus! (the Browns in 2018, the Raiders in 2019) or a team that could use the free publicity as they work to try and sell us something.
Such is the case with the 2020 team(s): The Chargers and Rams, though it might not be the worst thing.
