The one thing that these numbers don't show is the type of pressure they typically bring.
Verse is a bull rusher, so often times his pressure is generated by pushing an OL back into the pocket. That's obviously disruptive, but it doesn't always translate to Verse getting his hands on the QB (hence, his relatively low sack totals).
Garrett regularly beats his man cleanly, giving him an unobstructed path to the QB. That is why he has 13 more sacks over the past 4 years than any other player in the NFL (67 total in last 66 games played).
