"That's one thing that I want to bring to this team, being physical, every play, relentless", Peterson said.
Coming off an 8-8 season, the Cardinals were hoping to rebound quickly with a new coach and quarterback.
Former Redskins coach Norv Turner used to run plays in certain games just so a defensive coordinator for an opponent a few weeks out had something to ponder.
But fresh off signing a new three-year contract with $30 million guaranteed, Johnson got what he wanted to start 2018.

Most importantly, Washington is now 1-0 on the season.
After Arizona's first three-and-out, Washington used up 9:06 in a 15-play, 73-yard drive, Peterson plowing in from the 1-yard line to make it 14-0.
"As much as we emphasize and we talk about the physicality and the effort", he said, "you've seen that throughout the four preseason games, attention to details, those kind of things". "All night, we were playing catch-up and that was really the issue, that we were never really able to get into a rhythm when we go behind".
On Washington's second touchdown drive in the first half, Smith picked up a first down on a fourth-down quarterback sneak, found tight end Jordan Reed for a 22-yard completion after avoiding pressure, scrambled seven yards on another play, and connected with Jamison Crowder for a 10-yard gain to the Arizona 4.More news: U.S. Imposes Sanctions on N.Korean IT Firms
"There's no reason to panic, but this is not OK, it's not acceptable", defensive tackle Corey Peters said.
"Everybody has to take a good look in the mirror and kind of point that finger at themselves and their responsibility in this", Peters said, "because when you fail at this level, that's not one person".
Arizona avoided a shutout when David Johnson ran 2 yards for a touchdown with 5:47 to play. But Washington let him carry the ball 26 times (for 96 yards).
Arizona's offense spent the first half sputtering in neutral, leading to boos from the home crowd. Thompson gained 65 yards in just five attempts, and caught a 13-yard touchdown pass. Outside of a couple of decent Johnson runs, the Cardinals had no running game to speak of, finishing the half with 36 total yards - one less than they had in penalties.
"We just didn't play the way we are capable of playing", said safety/nickel cornerback Budda Baker, whose 11 tackles tied Josh Bynes for a team high. "We've got to figure out a way to get points early, figure out a way to convert third downs".More news: World Cup champion goalie Hugo Lloris pleads guilty to drunken driving
Sam Bradford was uncharacteristically erratic, completing 20 of 34 for 153 yards with one interception. Johnson salvaged his day with a two-yard rushing score with less than six minutes remaining in the 24-6 loss.
