Just days after the Dallas Cowboys and defensive coordinator Rob Ryan parted ways, the team opted to hire ex-Tampa Bay DC Monte Kiffin. With him Kiffin brings a 4-3 defense, and a welcome departure from the as-of-late 3-4 defense Dallas has been using.

While the Cowboys have not officially announced the addition to the coaching staff, Kiffin supposedly met with the club today to sign the papers.

Kiffen, after spending 13 years with the Bucs, hasn’t coached in the NFL in four years. He coached college ball with his son, Lane, at the University of Tennessee and University of Southern California. After the Trojans’ Bowl game this year, Kiffin left his position to chase loftier ambitions in the pro ranks yet again.

He already has one Super Bowl ring with Tampa Bay.

Kiffin is known for his Tampa Two defense -- a spinoff of the Cover Two -- and the turnovers it consistently creates. With names like Ronde Barber and John Lynch in Kiffin’s arsenal, it’s hard to believe a spat between John Gruden and him caused so much discourse and Kiffen’s abrupt departure in ’08.

What can a defensive coordinator like Kiffin do for Cowboys like Morris Claiborne or Demarcus Ware? That remains to be seen. Will the Tampa 2 work in Dallas under coach Jason Garrett? Well, Kiffin is a 72-year old prospect starting anew with another team, so who knows. He’s not exactly playing with a defensive tackle like Warren Sapp. Brandon Carr and Claiborne leave a huge question mark at corner/safety.

If Kiffen works, kudos to the Cowboys’ front office, namely Garrett and Jerry Jones. If he fails? He may not have a second year to prove himself.

And neither will Garrett.
