CBS's Cold Case iced the competition in its debut Sunday while NBC notched promising numbers for its new Rob Lowe drama The Lyon's Den. Cold Case attracted 15.5 million viewers to lead the 8 pm hour, while Lyon's Den drew 12.5 million viewers to finish second at 10 pm (behind the Eye telepic 12 Mile Road). Meanwhile, David E. Kelley's retooled Practice — which featured a poignant story about a man who smelled — failed to impress with 10.2 million viewers.
