CHARLOTTE, N.C. - We hear it all time when we're talking about the Panther: 'Keep Pounding'. But where did the motto come from?

According to Panthers.com, former Panthers player and Coach Sam Mills started it. He used it in an emotional speech in 2004 before a playoff game against the Cowboys. Mills talked about commitment, dedication, team effort and never giving up. He asked his players to 'Keep Pounding'.

Mills died from cancer in 2005. Now the spirit of 'Keep Pounding' encourages cancer patients and survivors to keep pounding and overcome obstacles. If you've been to a game you've seen the Keep Pounding Drummer. The drummer is usually someone who's overcome some type of struggle.

We spoke to a local cancer survivor during the Panthers run to the Super Bowl. He shared what Keep Pounding means to him.
