Richard Sherman has said that players have to be responsible for their own actions.
The Seattle Seahawks have had more suspensions for breaking the NFL's rules on performance-enhancing substances since head coach Pete Carroll took charge of the team in 2010 than any other team in the league.
The cornerback, who successfully appealed against a four-game suspension in 2012, told reporters: "Guys are accountable 24/7. Guys have to be accountable for their actions. Guys have to always abide by the rules, which we only have three; take care of the team; no whining, no complaining; and be early.
"Those are the simplest rules ever. But guys have really embraced it this year and really taken care of one another, made sure that we kept one another out of trouble and made good decisions all year long. That's what it came out to.
"It came out in a meeting earlier in the season with all the nonsense that was going on, and guys really made a point to correct the mistakes that other guys had made and make sure they're accountable for their actions."
The Seahawks face the Denver Broncos in the Super Bowl on Sunday.
