There are probably 30 top tier IDP players. Look at the scoring system and figure out who's most valuable. Taylor (MIA), Urlacher, Adrian Wilson are the glam picks, but there are some really solid performers well below the radar. A few late round guys once all the well-knowns are gone would be: Defensive Line: Will Smith (NO), Tamba Hali (KC), and Trant Cole (PHIL) Linebackers: AJ Hawk (GB), Demarcus Ware (DALL), London Fletcher (WASH) Defensive Backs: Sean Jones (CLEV), Charles Tillman (CHI), and Antoine Winfield (MIN). All of those players are productive and far enough out of the general populaton's knowledge that you can wait a long time, get tremendous depth and value at other positions, and get a solid, if unknown, defense.
