having 4 at the back when only 3 are necessary is a waste. Dont go with 3 DCs then, line up with a DL-DC-DR...that will make your lone DC man mark his lone ST while your DL/DR take his wingers. Why quadruple mark a lone ST in your example? fullbacks to defend wingers? I thought your own ML/MR can do that. or use DML/DMR.
