Its because of allowing the dB's to play tight man, allowing the lbs to roam free, allowing the d line to attack more than just play gap contain. Roby was also a huge factor in run force support, that allows the de on his side to attack more rather than just play outside contain. It was crazy watching Roby just shut down an entire side of the field run and pass wise, allowing others to attack. I urge everyone to really focus on that for a few plays next week.
