No, we do.....they couldn't go small because Brook/KG wouldn't allow that. They started to win when they went small and changed the way they play.....that's not possible with a Brook/KG/PP front line.
No, we don't. They are playing well now but that doesn't mean this would not have happened with Brook in the lineup, Worst case scenario is that they could have played different lineups depending on the teams they were playing.
