ive seen ray competing in the 80's , i could see then he already was better than jay. i guess jay had better marketing team behind him + ray had a bad rep because he was sentenced for armed robbery.
I heard Jay was always envious of his brother Ray's arms. And because so, Jay would put visine drops in Ray's Shirley temple while growing up. Ray was always sick and no one knew why. It most likely cost Ray many Mr. Olympia's.
