Basically the Subject says it all - the Game should allow players to have multiple traits.
I have had many situations where I wanted to give a player multiple traits.
If you want to keep this special, maybe we could throw in a cool restriction -
Each team designates their "Franchise Player", and he is the only player on the team allowed to have multiple Traits. Maybe? I dont see a reason to restrict, but I thought maybe there was a reason why we can't already assign more than one trait to a single player
It's no stretch at all to imagine, for ex:
EX: QB who is both a "GameManager" and a "FilmGeek"
