If the Cowboys could acquire a good 3 technique in free agency, they would have the makings of an excellent line.
Crawford - Ratliff - Free Agent - Ware
Ware is an elite edge rusher. All they need now is a tackle who can beat the one-on-one guard match ups that the 4-3 under alignment forces.
The position Ratliff would have to play is similar to the one he plays now, and he presents problems that most nose tackles do not.
"Many of the greatest things man has achieved are not the result of consciously directed thought, and still less the product of a deliberately coordinated effort of many individuals, but of a process in which the individual plays a part which he can never fully understand." - Friedrich Hayek
