Preheat grill to medium-low heat. Rub ribs with Sweet & Smoky Rub. Wrap ribs with 2 to 3 layers of heavy duty aluminum foil, sealing ends tightly. Grill ribs over indirect heat 2 to 3 hours or until tender.
Meanwhile, microwave sweet potatoes on HIGH 7 minutes or until almost tender, turning sweet potatoes over halfway through cooking. Let stand 2 minutes. Cut sweet potatoes into wedges.
Remove foil from ribs. Transfer to lit side of grill over medium-high heat 3 to 4 minutes per side or until browned, brushing with some of the barbecue sauce. Grill sweet potatoes 2 minutes per side or until lightly browned, brushing with remaining barbecue sauce.
