I suppose it's a different mentality for Brady in first team football where results are everything. In youth games the emphasis is encouraging young players to learn good habits, technique and team play, the performance is the most important thing which reduces the need to alter the team or style of play.
At the moment the first team is like a new group of players at the start of the season. I feel confident that JB and Co. are smart enough to make appropriate changes when the team is playing is the way they want.
He has already severely criticised some players after the Swindon game so perhaps he has the wherewithal to manage players in the right manner after a defeat? At the moment the team are his 'revitalised' players so they are for now 'great' players. He has said he will do everything possible to ensure survival in L1.
