I decided to simulate matches with this tactic. I've done half a season with Everton - should be a standard mid-table team.
After 19 games: Everton are 5th, with 9 wins, 5 draws, 5 losses. GD: 10 (36 for, 26 against)
For the second half of the season, I'm gonna reduce the passing to a short passing style, and pull the wing backs down but give them an attacking mentality...
