Porky is correct on almost all fronts. I would argue that the running game IS a talent issue. In the NFL, if you have a 7th round talent/ability RB you NEED to have a big mean dominant OLine. If you have a 1st round elite talent RB, you can still have a good attack with smaller quicker passblocking Linemen.
The Packers have both a 7th round talent RB AND a small agile passblocking Line. Bottom of the league rushing game year in and year out.
If you ask me, Spitz and Lang and maybe Dietrich-Smith are the only real players of the young bunch. Colledge, Giacomini, Barbre, and Wells are fringe NFL talent, and are guys who may not get an NFL job after there time with Green Bay.
It is possible to have success with Grant, but we have to be more deceptive with the rushing game. The passing formations need to be the same formations you run form. Our runs are very poorly designed and the Defense picks up on them quite easily before the snap., and that is on McCarthy. A little more creativity from the run wouldn't hurt.
But good post by Porky, and alot of people quickly forget the basis of the NFL is to get your team in full order late in the season. Look at the story of the Super Bowl teams of the last 4-5 years. They were all teams that had very rocky starts/middle of seasons. They were middle of the pack type teams and then picked it up when it counts, in December/January.
I think the Packers are a team that can make a run in the Playoffs. The passing game is Top 5 in the NFL, and the Defense is coming along and could become a force late in the season. It all falls on McCarthy and the staff to have the players ready to go and to be calling the right plays. Should be fun to watch....
