I love this pick... essentially moving up to get Best, and then falling back 27 spots in the 4th and getting OT Fox of Miami. The trade looks like a success.
I know the Lions are in great need of an OLB or MLB, but getting a good OT in the late 4th that can sit and learn for 1-2 years behind Backus/Jansen.
Fox has a full year to prove he's the future at tackle... if it works then Lions first round next year can be defense again instead of OT. If it doesn't... just a fourth round pick for the 2-deep.
Looks like free agency for that LB and another CB. But the line is "good enough" for 2010.
