Hoskins/Waters and Powell as de facto wingers have proved to be reasonable options; both looked ok in recent away games. In the last Home game both Hoskins and Powell did ok! Don't quite see why you are so concerned about JFH infexibility on team selection/tactics etc.
Not sure why you're quoting an old post; but when I posted this back in mid October, Powell had only ever been useless and Hoskins was still unfit. Waters looks like a lower level league 2 player when he's on the right wing for us. My point was how we have seen two full backs, several centre mids and an aging striker all play on the wing at some stage this season as opposed to adapting the formation.
At the moment we have what we have so its simple; make the best use of the players available.
Genius. Maybe we should try and outscore the opposition as well?
