Two total non-factors IMO. We need a strong 4 man rush. Right now we have one piece of this, the 3 technique in D. Robinson, if he develops. Philly showed the blueprint, have a DT so big, strong, and disruptive that he eats 2 blockers and still caves the front of the line, leaving the other 3 rushers in 1 on 1s.
If the FO agrees that D. Rob is the 3 of the future, they need to fill out the other spots. Consider they probably think BJ and Zaven tag-team one edge spot, that leaves the power DT and a dominating edge rusher to be gained in this offseason.
