Process pretzels in Manual Food Processor until coarsely chopped. Form cheese mixture into football shape on a platter; coat with pretzel crumbs. Cut string cheese in half lengthwise. Cut one of the halves into thirds crosswise. Arrange cheese on football to look like laces. Press down into cream cheese mixture. Serve with crackers and additional pretzels, if you’d like.
