What roles to use, is depending on how I instruct my attacking winger to play. If I ask my attacking wingers to stay wide, so, I will play with (FB) in support duty. But, if I ask my attacking wingers to sit narrower and cut inside, I will play with wing backs in support duty. In some certain circumstances, I give my side backs defend duty, as I need them to shut the shop. Lately, I think it would be good, if you play (CWB) with support duty.
