The Lions only have three player that started with the Lions that are Hall Of Famers under the Ford Family Ownership... Barry Sanders, Charlie Sanders and Lem Barney. No other players are worthy to be on the banner.
I am also a fan of arbitrary restrictions, but instead of your lets go with players that have a last name that start with "S" and played a position the had "Back" in it's name.
So Barry Sanders, Billy Sims, Joe Schmidt, Corey Schlesinger, and of course Luke Staley
