GREEN BAY – Young players and veterans may have different objectives during OTA practices, but all benefit from the non-padded, on-field spring work.

As the Packers embark on Week 2 of OTAs, Head Coach Mike McCarthy discussed what players at various stages of their careers get out of OTAs.

For the rookies, it's an introduction to the playbook.

"We're pushing through these installations, making sure our rookies have everything before they leave at the end of minicamp," McCarthy said prior to Thursday's open practice.

One of those rookies, first-round draft pick Kevin King, is unable to participate due to the University of Washington's school calendar, so he is communicating via screen time with cornerbacks coach Joe Whitt on what he's missing.

For other young players, development can be rapid, from adding muscle mass in the weight room to schematic understanding in the classroom, now that they're no longer rookies just trying to find their way.

"There are always things to work on," McCarthy said, even in a practice environment without pads, which will go on in training camp. "We spend the majority of our time on fundamentals. This is where you get the biggest jump."

For the veterans, it's about stepping forward when called upon, particularly this year after the Packers had more seasoned players than usual depart in free agency.

"This time of year is an incredible opportunity for veterans to grow in the area of leadership," McCarthy said. "They come back as experts in their craft."
