The really jarring thing that article points out is that Woodley is the highest paid defensive player in franchise history. That salary, Woodley's inability to actually make an impact on a football game in the past three years, and Jason Worilds' big contract all came together to spell the end for The Wood.
The Steelers' OLB depth, before the draft and free agency, include Worilds and Jarvis Jones. Yikes. Expect that to change in the next month.
