In the 2007 offseason, with longtime head coach Bill Cowher resigning after 15 seasons and Mike Tomlin taking over the reins, the Steelers controversially cut Joey Porter for salary cap reasons. Although the Steelers drafted two linebackers with their first two picks that year (Lawrence Timmons and LaMarr Woodley), Harrison was appointed the starter in place of Porter. The decision would ultimately pay off, as Harrison would go on to have a breakout season, making All-Pro Second Team and earning his first trip to the Pro Bowl as a starter on the AFC squad.
