Depth chart changes for @Steelers: Tuitt now starter at RDE; CThomas is Heyward's backup; DHB is AB's backup; Blake now Gay's backup— Bob Labriola (@BobLabriola) December 16, 2014
It was expected at some point in 2014. Steelers rookie defensive end Stephon Tuitt has been quietly improving throughout the year, and heading into Week 16, he has passed veteran Cam Thomas at the top of the team's depth chart at right defensive end.
Brett Keisel was lost for the season during Week 13, and Thomas had gotten the starting nod immediately. Tuitt got the start last week, and it appears he will continue doing so in the team's final two games this year, starting with Week 16 against Kansas City. Recently signed DE Clifton Geathers is listed as Tuitt's back-up with Thomas only being listed behind Cameron Heyward on the depth chart.
Cornerback Antwon Blake is listed behind William Gay at left cornerback, with Ike Taylor and Brice McCain, in that order, listed at the right cornerback position.
Darrius Heyward-Bey also moved up the depth chart, according to Steelers Digest editor Bob Labriola. He is now listed as Antonio Brown's back-up, with Justin Brown behind him. Lance Moore is behind Markus Wheaton for the team's other starting wide receiver position and rookie Martavis Bryant is behind Moore.
