in 5 seasons harrison has 4 sacks with 2,5 coming as a DT in the 4-3.
in 4 seasons b.williams has 5,5 sacks as a 3-4 NT.
TBH if you compare williams 4 years as a NT to harrison 4 years as a NT with the jets then williams edges out....
also id say that landon collins and signing janoris jenkins while drafting a guy like eli apple played a pretty big role as well.
that JPP fella being a year removed from him hand injury also helped out i guess....
