Seeing as it is is all the rage in the NFL, why hasn't anyone become adept at stopping the wildcat formation.  Specifically, when the franchise QB is sitting out at the WR position.  I still haven't seen a a cornerback give a hard jam to one of those QB's sitting out on the edge.  Wouldn't you think that once a CB knocks one of these franchise Qb's on their butts the Wildcat would fade into the sunset?
