Remove skin from all chicken pieces. Place 4 pieces of chicken in resealable plastic bag. Pour 12 oz. of the dressing over chicken in bag. Repeat for other 4 pieces. Seal bags, turning repeatedly to coat all chicken pieces well. Refrigerate both bags at least 1 hour to marinate.
Preheat oven to 400°F. Pour breadcrumbs into a large baggie and add 2 chicken pieces at a time. Shake well to coat. Add more breadcrumbs as needed to coat all the chicken.
Arrange on baking sheet. Sprinkle any remaining coating from baggie over chicken.
