The thing is, Suh HAS traditionally gotten to the QB - http://www.espn.com/nfl/player/stats/_/id/13234/ndamukong-suh. Also, note the ridiculous stuff and passes defensed totals for an interior d-lineman. The numbers are in decline, of course, but they're still good.
Also: "The big DT tallied 15.5 sacks and 181 combined tackles in his time in Miami, despite eating up double teams constantly. Since 2010, he ranks second among NFL DTs in sacks (51.5), first in QB hits (147), second in total pressures (381.5) and first in tackles for loss (103)."
