Rookie quarterback Josh Rosen (No. 3) leads the huddle during the first OTA session on Tuesday.
Josh Rosen referred to last weekend's rookie minicamp as an extension of college, because the majority of players participating were getting their feet wet at the professional level.
The first-round pick graduated to the big-time on Tuesday. The Cardinals held their first organized team activity – OTA -- of the offseason, mixing in the rookies with the veterans.
Rosen was put to work extensively because fellow quarterback Mike Glennon left practice early due to illness. Left tackle D.J. Humphries was impressed by Rosen's composure.
"He stepped into the huddle and had a lot of pizazz," Humphries said. "He didn't seem like he was choked up at all. His voice didn't crack. He wasn't talking low. He was excited. He asserted himself into the huddle, and I was excited to see that."
Cardinals coach Steve Wilks said "Josh looked great," complimenting his timing throws to tight ends, in particular. Wilks was pleased with the way all of the draft picks assimilated.
"That class didn't seem out of place today," Wilks said. "That's the most important thing."
Running back Chase Edmonds said there was a lot running through his mind during practice, and he had to remind himself to stay calm and remember the playbook. But it wasn't lost on him that he was now alongside running back David Johnson and other NFL stars for the first time.
"I live for stuff like that," Edmonds said, "to compete against the best."
Wilks was happy with the pace of practice, which finished 22 minutes ahead of schedule. The coaches are constantly preaching for the players to move decisively.
"I thought the first day was pretty good," Wilks said. "The tempo and urgency was there."
HUMPHRIES SEES LIVE ACTION
Humphries is making progress in his return from the serious knee injury he suffered in November against the Seahawks.
While Humphries avoided a torn ACL, the recovery from a dislocated kneecap and an injured MCL has still been extensive.
Humphries said he took live reps on Tuesday for the first time since the injury. He didn't take every snap with the first team, substituting out to keep the workload lower, but said he was able to participate in every drill.
"It's been a long road," Humphries said. "I'm just happy to be back on the grass, get out there getting in front of people, sweating with the guys."
WILKS CONFIDENT IN KIRK'S CHARACTER
Second-round pick Christian Kirk was charged with property damage and disorderly conduct after an incident outside the Waste Management Phoenix Open back in February.
Wilks reiterated on Tuesday that the team knew about the situation before the draft. The case is still pending.
"We did our own independent research on it and we felt very good about the information that we received," Wilks said. "That's why we moved forward and really drafted him. As I stated before, we want to bring in great character guys, and I think Christian is one of those guys."
