DJ is very fast and mobile. Hes aware of what is going on around him. The difference between DJ and DT is that DT was a better pass rusher while DJ is more for coverage. That is why he will not get as many sacks as DT. DJ can make the stop when we need it. I honestly think DJ will be more like Edwards cuz of his gameplay so far and Donnie is there to teach him.
If DJ can get the pass rush down like DT did then DJ can be as good as DT. DJ has a long way to go and alot of years to do it.
