The Packers were one of the youngest NFL teams last season. They ended up leading the league in games played by rookies with 66. LB A.J. Hawk and OL Daryn Colledge got deserved NFL all-rookie team honors, but WR Greg Jennings didn't deserve it. Jennings was one of the worst receivers in the NFL last season, ending with his last game vs. Minnesota when he only caught 1 of 13 passes thrown his way. His first few games, prior to his injury, were very good, but he never played well after his return. It would have been very surprising if Jennings was a strong player in his rookie season, but he really has a lot of room for improvement in 2007.
