The Dallas Cowboys have a really good defensive line. It’s weird to say that because for years, that has been far from the truth. Oh, they would have a DeMarcus Ware here and a Jay Ratliff there, but overall the depth was sprinkled with quite a bit of rub-a-dub scrubs. The middle was manned by players like Nick Hayden and Justin Hamilton, who were admirable at times, but a liability most others. And even the good ones weren’t all that good. George Selvie, Jeremy Mincey, and Benson Mayowa all at one point led the Cowboys' edge rushers in sacks for a given season.
