You are looking for Marx Play Action Football. The players were approximately 4 to 5 inches tall in red and yellow. The field was a large mat you would spread out on the floor. It had a combination QB/K with styrofoam footballs. The running back had a wind up base and the defenders had bases you would push to make a TACKLE, literally. The offensive/defensive lineman had 3 holes in their bases and a plastic green line of scrimmage with small notches or pegs the lineman would set up on. Depending on how they were set the offensive line would swing open like a door when the back hit the hole. There is one for sale on ebay now.
