If there was one clear priority over all others for the Pittsburgh Steelers this offseason, you could argue that it was improving the speed of the inside linebacking corps, which lagged behind the standards of the NFL today last season. Vince Williams is a prototypical buck from years past, and Jon Bostic did not live up to the athleticism now demanded from the mack.
So they started off by signing Mark Barron in free agency, a starter with a hybrid role who was originally drafted as a safety before moving to the second level a few years ago.
