In the first few weeks, the biggest concern for the Packers was their depth at defensive tackle. With three key injuries by week 5 (DT Donnell Washington, DT James Lee, and DT Grady Jackson), it was a big problem. Well the problem is back. Lee is now on IR and gone for the season, he missed the last couple of games anyway, and Jackson has reaggravated/reinjured his knee and needs more surgery. Undrafted rookie DT Colin Cole made his first appearance as a Packer last week in Minnesota for some added depth. Jackson is putting his needed (no pun intended) surgery and play through the rest of the season. Teams seem to love to run away from Jackson, so if Jackson stops playing it could be a very quick postseason. The most likely first round opponent, Carolina, isn't a very good running team (now starting their 4th string RB Nick Goings), unfortunatley the likely 2nd round opponent, Atlanta, is a very good running team although their big RB T.J. Duckett will probably play his first game in a month in the playoffs after undergoing December knee surgery.
Should the Packers sit out their players in Chicago? I hope not. Last season, Denver came into Green Bay in week 17 to play a meaningless game, sat all their regulars, and then got blown out in the playoffs. Injured players like LB Na'il Diggs and Jackson should sit, but the rest of the team should play at least the first half.
