(CNN)Given the multi-billion dollar nature of the business, you might think that no expense would be spared in ensuring NFL players' every need is taken care of. If so, think again.
In a survey published by the NFL Players' Association (NFLPA) on Wednesday, 1,300 players provided feedback on the league's 32 teams, which were then ranked in a variety of categories.
Look away now if you're a fan of the Los Angeles Chargers, the Arizona Cardinals or the Washington Commanders.
NFL players rated teams in the NFLPA's "Club Report Cards" survey based on their treatment of families, nutrition, weight room, strength and conditioning staff, training room, training staff and locker room. They also provided feedback specific to each team.
The Minnesota Vikings were ranked as the best overall: the NFLPA report pointing to the franchise's newly built, state-of-the-art facility, calling the team a "shining example of what is possible when a concerted investment is made in both staffing and facilities."
The Miami Dolphins came second, with the only critique being that players would "like a better post-game family area with more accessibility for players' families." The Las Vegas Raiders finished third.
At the other end of the scale, the Chargers, Cardinals and Commanders comprised the bottom three.
The Commanders finished last, with the franchise handed an F-minus for their training room, locker room and team travel, while also getting an F for treatment of families.
Complaints from players included an understaffed training room, undersized hot and cold tubs for player recovery, not enough personal space in the locker room and lack of warm water and issues with poor drainage in the showers.
The Chargers and Cardinals didn't immediately respond to CNN's request for comment.
In a statement sent to CNN, the Commanders said: "Player health and safety is our top priority, and we continue to invest in our facilities, including a new practice field, new turf in the practice bubble and increased meeting room space. We know there is more to do, and we regularly talk with our players about ways to improve their work environment and the experience for their families."
