Tom Brady or Joe Namath rookie cards what is the better bet longrun?

Besides some NY kids who may have had fathers who idolized Namath, I don't get the sense any Millennial or younger know or care who he is nor will care about any of the stories, etc. What was considered flamboyant and outrageous back then probably sounds tame and lame compared to the trouble modern athletes get into today and the ease in which its documented in social media.

I wonder if Sammy Baugh's lack of price movement in the past decade is a good analogy indicator of how Namath's cards will perform once all the Boomers who saw him play are no longer around driving demand and prices up.
