The Cardinals have put themselves into playoff contention over recent weeks, and currently sit above the San Francisco 49ers in the NFC West with a 7-4 record.
If they are to make the post-season, Peterson has said that the team must win every game they play from this point onwards.
He told the club's website: "We're just in the hunt right now. Every game from now is a playoff game. We've just got to win every ball game.
"We need to have everybody communicating well and making sure people are on the same page. I think we're clicking at the right time. We could be remembered for the games we win in November and December."
The Cardinals have not featured in the post-season since winning their division in 2009, and they take on the Philadelphia Eagles this Sunday.
