"We've kind of changed our techniques (from) years past until now," said Keisel, who led the Steelers by a wide margin with 41 pressures in 2012. "In years past, when we had James (Harrison) and LaMarr (Woodley), it was mostly just push the pocket, try to collapse the pocket, make the quarterback flush and those guys would be there to clean him up. That's what we were taught."
