The Dallas Cowboys' attempt to switch from a 3-4 base defense to a 4-3 Tampa 2 scheme this past season was an abject failure. They intend to stick with that scheme in '14, but they demoted Monte Kiffin from defensive coordinator to assistant head coach/defense and promoted Rod Marinelli from D-line coach to DC.
