Unroll dough. Press or roll out on bottom of greased 13x9-inch baking sheet. (You can use corn meal to prevent sticking if needed) Shape dough into a large football shape. Place 6 pieces of String cheese along inside edges of crust. Fold sides of crust over and around cheese; press crust edges to seal.
Top with pizza sauce, pepperoni and shredded cheese. Be sure to place the pepperoni near the center of the pizza and try not to double the layers. Bake in preheated 425°F oven 15 minutes or until crust is golden and cheese is melted.
While the pizza is in the oven, cut 2 pieces of string cheese into strips to make the football laces. Place the laces on top of the pizza immediately after removing from the oven. Then cut and serve.
