More on Dallas' fallback plan at DT

In previewing the Dallas Cowboys' 2013 season, some were of the belief that the shift to Monte Kiffin's defensive system could serve to resuscitate DT Jay Ratliff's career: his play had been on the decline in recent campaigns, and he missed 10 games in 2012 due to a variety of injuries. Unfortunately, things haven't gotten off to a very good start at training camp, as Ratliff was placed on the PUP list thanks to a hamstring strain that occurred during conditioning tests, according to ESPNDallas.com. The injury may be a minor one, but it's not a great sign. So what happens if Ratliff isn't available in the early going (or later, due to another injury) this season?
