The players Arizona named inactive -- Eric Green, Tim Castille, Victor Hobson, Elliot Vallejo, Brandon Keith, Alan Branch and Jerame Tuman -- have generally not been significant contributors. Castille filled in as a tight end against the Panthers in Week 8, right before the Cardinals signed Stephen Spach, who is now on injured reserve.
Having Doucet active gives the Cardinals additional insurance if Boldin's hamstring becomes a problem. Arrington has mostly contributed in four-receiver packages and as a kick returner. The Cardinals haven't gone with four receivers nearly as much during the playoffs, in part because they have been leading those games much of the way.
