SB Nation's Lions community, Pride of Detroit, has their report card and it's not bad. POD used a formula to grade each pick and averaged it out.
Overall, I gave the Lions a B simply for the picks they made. Again, if you take into account all of the picks the Lions used to acquire proven players, the overall grade would easily be bumped up to an A for me. For the picks alone, though, I like that Suh and Best will be able to contribute from day one, that Spievey and Fox have the potential to develop into solid players over time, and that the seventh-round picks weren't completely out there or anything.
When draft picks used to acquire veteran players were taken into account, POD grades it an A.
Here are all the Lions draft picks:
DT Ndamukong Suh
RB Jahvid Best
CB Amari Spievey
OT Jason Fox
DE Willie Young
WR Tim Toone
POD readers are currently split on the draft class with about half grading it an A and the other half a B.
