The request was hidden in the answers from Packers coach Mike McCarthy at his Thursday news conference. If Green Bay is to get back to the big game, McCarthy needs more good players, a deeper bench.  The first 22 players for the Packers were pretty strong in the 2017 and things looked good — until they started getting hurt.  Quarterback Aaron Rodgers’ play has covered up a lot of team weaknesses.  McCarthy hasn’t said it, but he is re-shaping his coaching staff and now he wants the new general manager to change the team’s approach to filling its bench, signing a few free agents and quit letting team leaders like Julius Peppers, T.J. Lang and Micah Hyde go elsewhere.
