Even though the team lost DE Dave Tollefson in free agency, DT Rocky Bernard thinks the line can maintain its success. “Depth is big,” Bernard said. “Dave was a big part of what we did last year. If we can all stay healthy, we can have the same success.” DC Perry Fewell said SLB/DE Mathias Kiwanuka will continue to see time on the line, but he doesn’t know if it will be more than 2011 when he primarily played SLB.
