I’m not convinced that Burton fits that list. Sure he can add a 40/20 to swing momentum, but those other 2 are tackle breakers. Burton probably could easily go back to the centres and be as useful as he was and all 3 could potentially make a move to fullback. Burton seems a bit like the Mahoney signing at the bulldogs where it was the best they could get at the time, probably on the higher side salary wise, but now are surplus to requirementsBut those three arent just centres though are they. All three are game breakers that can also play multiple positions
