Keith Wortman possibly???Actually I think blocks like that were legal back then. Can you read the begining of the last name on the Cardinal's lineman? I'm wondering if it was Conrad Dobler who was known as the dirtiest player in the game.
I just realized the other day that 3 of the 4 rookie cards of the Cowboys famous D-line of that era were all in 1976 Topps. Martin, Jones and White. Pretty perceptive for a card OG (Old Goat) like me. LMAO!!!
