Heat oven to 350°F (325°F for dark or nonstick pan). Line 9-inch square pan with foil, letting foil hang 2 inches over sides of pan. Grease bottom only of foil with shortening or cooking spray.
In medium bowl, stir brownie mix, chocolate syrup, oil, water and eggs until well blended. Spread in pan.
Bake 35 to 40 minutes or until toothpick inserted 2 inches from side of pan comes out almost clean. Cool completely, about 1 1/2 hours.
Using foil to lift, remove brownies from pan. With football-shaped cookie cutter, cut brownies into football shapes. Spread frosting on brownies. Pipe on decorating icing to look like football laces.
