For those of you who are curious what PFF thinks about the Pats defense (and I have a lot of issues with PFF) here are the individual player grades and positional rank among those with at least 20% snaps. Positional group classifications by PFF so KVN is lumped in with ILBs and Bryant is considered a slot corner.
