Do the Colts have the most underrated secondary in the NFL?

I believe no other secondary comes close in being underrated. Everybody knows who Bob Sanders is, but the rest of them are good solid players that only colts fans know about. Just look at their stats from last season and it's pretty self explanatory. They ranked second against the p, first against receivers, and they tied second in interceptions. If you ask anybody who they think has the best secondary, most likely they will say Denver, Dallas, or Philly but never Indy.
