PITTSBURGH -- Dan McCullers is not just a defensive tackle. He's a walking baobab tree with a reach as wide as an IMAX movie screen.
The mere presence of this mammoth, 6-foot-7, 352-pound man causes a double take, even when you see him every day.
That's why McCullers' production -- 10 tackles in 21 career games -- is a bit curious, prompting defensive end Cam Heyward to stress at organized team activities that McCullers must "put it together" and "play humongous" in his third season. The Pittsburgh Steelers obviously expect the same after letting starting nose tackle Steve McLendon walk this offseason.
