GREEN BAY – First-round draft pick Damarious Randall did not participate in Friday’s rookie-camp practice, but Packers Head Coach Mike McCarthy expressed no concern.

“Damarious, just being smart with him. It’s something minor. He’ll be ready to go before next week,” McCarthy said.

The Packers took a 61-man roster into the first day of the weekend rookie orientation. Second-round pick Quinten Rollins punctuated the practice by intercepting a pass from fifth-round pick Brett Hundley that was intended for third-round pick Ty Montgomery.

“This is a great time of year. You get in the team meeting room. The energy, you can just feel it. We did a lot of movement drills, mostly for guys we don’t have a lot of information on,” McCarthy said.

Montgomery was one of the stars of the movement drills.

“He has a ton of explosion. I thought he definitely stood out today,” McCarthy said.

The rookies will join Packers veterans in the offseason conditioning program on Monday.

“When they get in the weight room on Monday, you’re going to see a significant gap between the rookies and the veterans,” McCarthy said.

Rookie camp is mostly about evaluation. The camp includes 25 tryout players.

“We’re looking for football players. We’re looking for guys who jump out at you. We’ll have a similar format tomorrow. This is all about building the best 90-man roster we can,” McCarthy said.

Recent rookie camps have produced several long-shot players that have made the team’s final roster. McCarthy said he expects similar results this year.

“We’re pretty much a 25 (age) program. We don’t deviate from that. About 32 percent of your football team (90-man roster) is in that room,” he said.

McCarthy’s message to the young players?

“It’s time to throw your 40-yard dash out the window. We’re looking for the right people to add to our football team. Change is constant,” he said.
