Contrary to popular belief, marinating doesn’t really make steak more tender. Go ahead scroll right down to the comment section and put up your dukes if you want. But I have read many geeky culinary science books and issues of Cooks Illustrated and listened to hours of the splendid table, and I can verify that marinade only permeates the outer layer of the meat, so it only really breaks down the outer cells of the steak. The texture difference will be negligible. Marinating is really only mostly for flavor.
