Mel Kiper was pretty high on the Packers draft class compared to the rest of his grades. He gave out no A's, but did give out three A-'s (Cincinnati Bengals, St. Louis Rams and Baltimore Ravens). The Packers were there in the next grouping.
Kiper gave the Packers a B on filling needs and an A on getting value.
Here are some snippets from what Kiper had to say. The whole report can be found here (ESPN Insider required).
I love what Green Bay got out of this draft, particularly at two spots -- defensive end and running back. Datone Jones is a perfect scheme-fit for the defense.
One sleeper here is Charles Johnson from Grand Valley State. I thought he might come off much earlier than No. 216. Green Bay did well with its early picks, and that's plenty.
Kiper nails it on the Packers draft. He has a great understanding of what the Packers really needed to do in this draft and how they accomplished it. Kiper's grade seems entirely fair on both need and value. Adding Johnathan Franklin and Eddie Lacy in the middle rounds added great value.
The final note about Johnson is interesting. It's unusual for seventh-round picks to have an impact, but it seems that Johnson has the skill set to compete. Granted, it will take a lot of proving it on the field, but the potential is there for Johnson to succeed.
