Heat oven to 325°F. Spray 13x9-inch (3-quart) glass baking dish with cooking spray. In large bowl, mix uncooked rice, both soups and water; pour into baking dish.
Arrange chicken, skin side up, over rice mixture. Brush chicken with melted butter; drizzle with any remaining butter. Sprinkle with paprika. Cover tightly with foil.
Bake 1 1/2 hours. Uncover; bake 20 to 30 minutes longer or until chicken is fork-tender, its juices run clear and skin is slightly crisp.
