The Panthers really jumped in on associating Mills with the franchise to him coaching for the organization right after his playing days.NFL HOF doesn't ask players to select a team to represent them as they are inducted, that's the MLB HOF--due to all players busts wearing caps. The NFL just has a plain head bust. I agree it was a mistake to let Mills go, he was the team's best player, but the Saints were in the old "burn it all down" mode that not surprisingly lasted the rest of the 90's rather than the 1-3 years they were hoping.
It's weird when you google image Sam, 75% of the pics are of him as a Panther, when in reality he played 75% of his career here. For what it's worth, his family asked Jim Mora to be the presenter at the HOF, and the HOF website shows only Saints pics: https://www.profootballhof.com/players/sam-mills/
