Roy Williams being shopped around by the Lions?

[Carnage]

According to the Wiretap, the Lions are shopping around Roy Williams in an effort to get Matt Ryan.

IMO, Ryan isn't worth the trouble of trading a Top-Tier WR. However, if the Lions are intent on trading Roy Williams in an effort to draft Ryan, the only teams I could see trading out would be:

Pick 4 (Raiders) - Add more options for JaMarcus Russell
Pick 5 (Chiefs) - Same as the above, but for Brodie Croyle
Pick 9 (Bengals) - Replacement for Chad Johnson perhaps?
