1. Prepare grill.
2. Combine first 9 ingredients in a bowl, stirring well. Loosen skin from chicken by inserting fingers, gently pushing between skin and meat; rub spice mixture evenly under skin over meat. Lightly coat skin with cooking spray. Place chicken, breast-side down, on a grill rack coated with cooking spray; grill 30 minutes or until a thermometer inserted in the thickest part registers 165°, turning twice. Let chicken stand 10 minutes. Remove skin; discard.
