In Rod Marinelli’s defense, the importance of a 3-technique defensive tackle in comparison to a 1-technique defensive tackle is pronounced. One player that has had to play both positions is Maliek Collins, and he appears to be better suited to the 3-tech. He was excellent in his rookie season, but once he was asked to play out of position, he took a step back in 2017. The Cowboys also have David Irving who played the 3-tech spot most of last year. The 1-tech position is kind of barrens.
Dallas loves versatility all across the depth chart.
