Mike McCarthy promised Wednesday to evaluate, make changes and learn from his team's gut-wrenching NFC Championship Game loss to the Seattle Seahawks.

The Green Bay Packers coach also delivered another promise.

"Every game you compete in is a unique experience, and the only way you benefit from that experience is you have to be able to learn from the victories and defeats. That's the mind-set of a champion," McCarthy said during his season wrap-up news conference. "That will never change. But the 2015 football team will not bear the burden of what happened in 2014 or before that. That's not the way we operate."

McCarthy's 30-minute session was light on specifics and devoid of any major announcements or staff shake-ups. Assistant coaches are off this week, and if McCarthy does plan on making changes — after two major special-teams gaffes contributed significantly to the season-ending loss, special teams coordinator Shawn Slocum's job security could be tenuous — he will do so after meeting with coaches starting next week.

"It's important to evaluate. I obviously haven't had that opportunity," McCarthy replied when asked about Slocum's job status. "We'll look at everything. We'll look at every job description, every job responsibility, performance — mine included — and we'll look to make changes."

Academic cheating on rise

Vice president of enforcement Jon Duncan said that the cases involve both prospective and incoming athletes trying to become eligible for college competition, and enrolled athletes receiving impermissible assistance from university and athletic department personnel.

Eighteen of the cases involve Division I schools, though NCAA policies preclude Duncan from revealing which programs are under investigation.
