News: Tolzien did not appear in a game during the 2014 season.
Impact: Tolzien appeared in three games during 2013 and even started two, but he was not needed at all in 2014 with starting quarterback Aaron Rodgers playing in every game after missing seven the year before. The Packers like Tolzien's potential and will likely give him another chance to challenge Matt Flynn for the backup duties during training camp.
News: Shields recorded 40 tackles (33 solo) and two interceptions over 14 games during the 2014 season.
Impact: Shields did not do as much in 2014 as he did the year before, but opposing offenses did not throw in his direction as often as they did previously. He earned his first Pro Bowl selection in 2014 and will head into next season as the Packers' top cornerback.
News: Williams made 71 tackles (61 solo) and intercepted three passes over 16 games during the 2014 season.
Impact: Williams' production in the tackle and sack departments dipped in 2014, but he played in every game for the third straight season and held up well in pass coverage. A free agent this offseason, it remains to be seen if he will Green Bay after speding the last eight seasons there.
