I was looking at this website and was blown away by some of the stuff for sale! Among the most interesting, is a 1985 Cardinals helmet with the #32 on the back. Is there any possibility that this was worn by Ottis Anderson? I checked Getty and there aren't any clear shots of Anderson that would lead me to dispute that he wore it, but the seller doesn't identify it as worn by him. If it was, for the price listed, it's a steal. Here is the link...
