Patrick Peterson has played on some very good teams during his nine-year career with the Cardinals.

The 2014 squad was 8-1 before quarterback Carson Palmer tore his ACL. The 2015 team won 13 games and finished a victory short of the Super Bowl.

It would take a huge leap for the Cardinals to compete with those iterations in 2020, but the veteran cornerback is ebullient in his belief that major strides could be coming.

"This is probably the best football team I've been a part of on paper," Peterson said on The Hyperice Lab podcast.

Like many, Peterson was impressed by the work of Steve Keim this offseason. The Cardinals' general manager has been widely praised for his roster makeover, which included a trade for All-Pro wide receiver DeAndre Hopkins and the choice of linebacker Isaiah Simmons in the first round of the draft.

"What we've been able to add to the team this year, what the front office has been able to accomplish this offseason (without) being able to see guys and not being able to be around, it's been second to none," Peterson said. "I mean, unbelievable."

Now Peterson believes the onus is on the players to see it through.

He said team leaders like himself, outside linebacker Chandler Jones, wide receiver Larry Fitzgerald and quarterback Kyler Murray must cultivate the type of atmosphere that can lead to a promising season, because "it's not just going to happen by putting a bunch of pieces together."

"It's going to come down to us to manage the locker room, manage the egos and make sure everybody is on the same page and understand that we have to commit to one another, believe in one another and trust one another," Peterson said. "If we do those three things, we can be in Tampa (for the Super Bowl) ready to face whoever, and ready to hopefully bring that Lombardi trophy, the first Lombardi trophy, home to Arizona."
