On PFF, Bresee (and other DL players) will get credit for pressures (and other traditional pass rush stats) whether they had to beat a blocker or not, but they also get tracked on how often they can win whenever they do engage with a blocker, even if it doesn't result in a pressure. Bresee had 324 total pass rush snaps, of which 295 was him rushing to beat a blocker in front of him (so 29 may have been stunts/screens/etc). Bresee only won against his blocker on 14 out of 295 snaps (4.7%).
