Potter would play better football, but he wouldn't get to two euros finals and a WC SF, he would play too open and try to out technical teams with players that are simply naturally more technically gifted than English players.
England need to find an identity and stick to it, which should be strong counter pressing and counter acting football, basically Liverpool when they had a midfield of Henderson and I think Milner.
The midfield is just there to do the fundamentals, wing backs and Wingers do the damage.
