NFP 2012 Draft Player Rankings..............
This list is too long to copy and paste so I'm just posting the link to the NFP Draft Page which shows the player rankings and their grades. There links to the key to the grading and players can be filtered by position.
Keep in mind that NFP does not rank according to where they feel a player will be drafted but based on their analysis and scouting reports how successful a player is likely to be in the NFL. Highlighting any individual player will bring you to his scouting report.
This may be as good a place to follow the draft and learn about the Bears picks around.
