The A's should ASSIGN names to players. Their real names? Don't matter. We wont remember or they get traded away muy pronto if good.
I think for fans it would be better if on the backs of uniforms ALL A's right fielders were give the name "R.Jackson". Center fielders "W.Mays". Catchers? "G.Tenace" and second string "R.Fosse". etc,etc,etc. You get the idea.
1st base ? "M.Mantle".
I tossed that in.
