Safety position underrated?

[SniperSB23]

Why is it that the safety position continues to be underrated in the NFL in both the draft and in free agency? They rarely get taken as high as they should and rarely get paid as much as they should. Yet you look at the four teams left in the NFL playoffs and there is only one common variable among them, great safeties. Four of the five safeties to receive votes for the All Pro team are in the conference championships (Reed, Polamalu, Wilson, and Mikell) and four of the six safeties in the Pro Bowl are from the teams in the conference championships (Dawkins instead of Mikell). I remember when Polamalu and Reed came out of college they were as surefire future NFL Pro Bowlers as you'll see. Yet Polamalu falls to the 16th pick, taken after 8 defensive lineman were off the board after Reed fell to 24th the year before. Makes no sense to me.
