Kyler Murray saw it on his phone the next day, the clip of Pro Bowl cornerback Patrick Peterson smiling, telling the world his rookie teammate was "very special" but that he "has to look away from '21.'"
"The next day," the quarterback said, "we got after it pretty good."
Murray said his goal in camp is to test Peterson "at least once a day."
"Honestly he's winning right now," Murray acknowledged. "He's making me pay for it. I've got to use it up. He's here, he's with us right now (before he has to sit out), and in my eyes he's the best corner in the game. For me to be able to see him out there every day, it's making everybody better."
Peterson has relished the interceptions he's already been able to get off Murray, but he's also quick to say Murray's potential impresses.
"He has all the intangibles to be an NFL great," Peterson said. "He has a (good) head on his shoulders, poise on the pocket, and a dual-threat quarterback who can throw? He can be dangerous."
The idea is that Peterson can specifically show Murray what elite cornerback play in the NFL looks like, preparing him for the regular season.
"This is the time" to test Peterson, Murray said. "Come the season, it'll be a little more, 'protect the ball.' "
CARDINALS MAKE ROSTER ADDS FOR DEPTH AT LINEBACKER, OFFENSIVE LINE, WIDE RECEIVER
Banged up at a couple of positions – including wide receiver, after Andy Isabella suffered a "minor" knee injury in Thursday's practice and could miss the preseason opener, coach Kliff Kingsbury said – the Cardinals made four additions to the roster Friday.
Signing were inside linebacker Hayes Pullard, wide receiver Issac Zico, and offensive linemen Parker Ehinger and Patrick Lawrence. The Cardinals had two open roster spots, so to clear further room the team released tackle Tarik Cole and running back Xavier Turner.
Pullard played in 22 games the past two seasons with the Chargers with 10 starts. A one-time seventh-round pick of the Browns, the four-year NFL veteran has 114 tackles in 46 career games. Ehinger was a 2016 fourth-round pick of the Chiefs who has also spent time with the Cowboys and Jaguars. Zico, a rookie, was with the Titans this offseason, while Lawrence is also an undrafted rookie.
SLIMMED-DOWN SHIPLEY WOULD LIKE TO KNOW CENTER DECISION SOON
Veteran center A.Q. Shipley, coming off the ACL tear he suffered a year ago this Sunday, said he is at 295 pounds, the lightest he's been. Normally, he'd be a little heavier, he said, but he took the weight off as he rehabbed his knee. The offseason time off he'd normally spend drinking and eating a little more before getting into shape was lost as he rehabbed straight through.
"I didn't have that luxury," he said.
But Shipley now is in the battle with Mason Cole for the starting center job. Shipley has said from the summer he expects to win it, and was asked about Kingsbury's statement that the starter might not be named until the end of the preseason.
"Do I like that? No I don't like that. Not one bit," Shipley said. "I'm here to win a job. The sooner I can, obviously I'd like that a lot better than hearing it in September. If you go into this job or this league or position questioning whether you can get it done or you can win the job, you're in the wrong spot. Until they tell me it's not mine, it's mine."
