I am not so sure what is the point of such a grading so early after the 06 draft other than to provide an entertaining read.
The key thing for all rookies is to take it up to another notch next season.
Basically the rookies are being graded on what they showed in their first year, and that is important to a certain degree. I'd rather he have done a review in at least 3 years time, where the grades will be more realistic.
For example, Jennings definitely was a great find for all the things he has shown. However, if he (God forbid!) doesn't improve much more than what he already is (and that was the knock on Jennings, he'll be good right away but may struggle to be great overtime, doesn't have the best long term potential) than that second round pick was a bit of a waste.
Ditto for Hawk, he showed potential but he still got blown up on plays and was probably out of position on other plays. IF he doesn't improve, then the pick was also a bit of a waste. The point of drafting at the top spots is to pick up stud players that can be difference makers every Sunday. Otherwise we could have gotten Greenway, Sims, etc. much lower and saved money too without much of a worry about drop off.
This draft will be made or broken in the next couple of years based on the amount of players that are still here (and contributing in a good - if not great- way) when the Packers become a playoff bound team.
