When the quarterback is sacked by a defensive lineman of inferior talent, due to a very talented defensive lineman that has taken up a double or triple team by the offensive line. The person credited with the sack is the shadow of a better player.
Jared Crick had many shadowsacks thanks to Ndamukong Suh taking up 3 offensive lineman at any given time in the game.
