Who's the Face of the Chicago Cubs?

For many of the 'Me Generation' the first face of the Chicago Cubs was Ryne Sandberg, then it was Sammy Sosa and for a majority of the last 10 years it was Kerry Wood. Bruce Miles wrote a detailed article on Ryan Dempster being "the total package" and made arguments for Dempster being the new face of the franchise. Miles rightfully stated that Carlos Zambrano "has seniority, but he's had his ups and downs with teammates, managers, the media and fans." The argument against Zambrano being the 'the top Cub' is justified, but Big Z has received the loudest ovation during player introductions at the Cubs Convention for the last three years. So who is the face of the Chicago National League Ball Club?
