The Cards brass seems to have fallen in love with their own press clippings when they were called 'innovators' for popularizing a dollar linebacker position. They say the league is moving in the direction of having fast versatile players. I can't imagine that having a bunch of jacks of all trades is preferable though.
You've taken a ProBowl, hall of fame caliber SS in Bucannon and made him into a 210 pound inside linebacker and called yourself a genius. Meanwhile, with Campbell gone and X Williams on the bench, you have the smallest D Line now and a bunch of 5'10" guys in the secondary.
Think of the baddest, most dominant defenses we've seen since the year 2000. They didn't win games by swarming you with a bunch of hummingbirds.
Reddick is the prototypical WILB. Let he and Dansby be ILB's. Golden and Jones are OLB's. Make Buc and Baker your safeties. (!) Peterson and a whole list of guys competing for CB1 and CB2, while Mathieu roams as nickel back. That's a scary defense.
