NBC greenlights six drama pilots

Include projects from David E. Kelley, Jerry Bruckheimer

After retreating from the drama series genre this season to launch five nights of the ill-fated "The Jay Leno Show" at 10 p.m., NBC is bringing in big drama guns for next fall, greenlighting pilots from David E. Kelley, Jerry Bruckheimer, "House" creator David Shore and "Without a Trace" creator Hank Steinberg.
