This tactic has worked fantastically for me with Newport Co in their first season. Signings were made, yes, but the results are fantastic.
As mentioned in the OP, possession statistics are often fairly low but the defence is solid enough and the offence is lethal.
After 21 games I'm 17 points clear at the top (17 games won, 4 drawn, 60 goals scored, 17 conceded). My rotated cluster of strikers including Fergus Bell (10 goals from 19 starts), Darryl Knights (8 goals from 10 starts), Martin Reilly (6 goals from 6 starts), Casey Thomas (8 goals form 14 starts) and most impressively Craig McAllister (18 goals from 19 starts) are the pick of the bunch.
Awesome tactic!
