Are 21 and 31 over-rated?

[5RINGS]

Found these numbers.

ER - Ed Reed
TP - Troy Polamalou (sp?)
ST - Sean Taylor
RW - Roy

Now I know ST and ER play FS but the numbers are interesting.

RW - 2 Picks, 5 Passes Defended, 14 Solo Tackles
ST - 0 Picks, 2 Passes Defended, 15 Solo Tackles
TP - 1 Pick, 4 Passes Defended, 14 Solo Tackles
ER - 1 Pick, 4 Passes Defended, 14 Solo Tackles

I don't know who else I would add to that list... Maybe Hope, or that dood in Arizona who is all over the place.
