The game is the main event and all eyes will be glued to the flat screen so there's no need to overdo it with decorations. A couple of special touches will be enough to get your guests in the spirit. Buy cup holders or beer cozies in team colors and write everyone's name on them so guests can keep track of their drinks. If you're dying for a little football imagery, stick to one item-a tablecloth, cocktail napkins or toothpicks are fun without being over the top.
