So since 2012, Bennett had 13 roughing type penalties, 66 penalties, 375 yards. Suh 7 roughing type penalties, 52 penalties, 270 yards.
One things this doesn't take into account is situational penalties, of which Bennett seems to have a huge problem with. I've been watching Suh fairly closely, and he doesn't seem to get penalties at critical times like Bennett.
