Monte Kiffin fields questions about the greatness of his Dallas defense one week, and how bad it is the next.
Brandon Carr goes from an elite cornerback befitting a $50 million contract to the guy who gave up 329 yards in one game to Detroit's Calvin Johnson.
It's a little hard to figure out what the Cowboys have on defense, since they've won games with takeaways and flashes of dominance but now carry the distinction of the only unit in league history to allow four 400-yard passers in one year.
That's with half the season left, and Drew Brees and Aaron Rodgers still to come.
Kiffin says it's been a "roller coaster" as Dallas prepares to face Minnesota at home on Sunday.
