I don't know of many homegrown players that do express much affinity out loud. Even the ones that had on-air stints at ESPN or NFL Network. Marshall Faulk, Reggie Wayne, Ryan Clark, Ed Reed. None of them stick out as being New Orleans cheerleaders or even live here now.
Faulk did all the time after Katrina. He did a lot of charity type stuff if I remember right and was always talking about Louisiana and how much they needed everyone’s support.
Ryan Clark is huge on LSU, but that’s all I hear from him regarding LA.
