In the year that the Kansas City Chiefs allowed Brandon Carr to walk away, the team's secondary began to fall apart. Injuries all over the place and the return from rehab for Eric Berry have weakened the overall unit and reliable guys like Kendrick Lewis and Brandon Flowers have already missed time in addition to notable back-ups like Jalil Brown and Jacques Reeves. Even new draft pick DeQuan Menzie is on Injured Reserve.

After Carr left via free agency for the Dallas Cowboys, the Chiefs have struggled to replicate last year's pass defense. But the Cowboys themselves are apparently hurting for bodies in the secondary after several injuries have lessened the unit's impact as well. That means that Carr is willing to step it up -- even potentially changing positions from safety to cornerback.

"If that's what we have to do for us to get our best 11 on their 11 and to get off the field and win ball games, I'm all for it," Carr said recently. "I came here with one thing in mind and that was to win ball games."

Carr already subbed for starter Gerald Sensabaugh in last weekend's game against Tampa Bay, and that could continue given the results and the need. Barry Church is already out for the season for Dallas as the other starting stafety.

It will be interesting to see how the Cowboys use Carr going forward and whether they're willing to allow their $50 million investment suddenly switch positions and lose the natural instincts and experience he's developed at corner. He was brought in to be a strength, but now it could be to plug the leak. That's an expensive tag for a fix.
