Halves need to 'own' the team before they start looking like they should. It could be they are just immature. Or they might feel that there are certain other members of the squad who 'own' the team, and are not able to take control of the side while this is the case.
To me, both look a little like the young kid in the team, not brave enough to step up & really show their ability just yet, held back by a little self confidence to some degree, more in tune with not being comfortable gambling that their ability is good enough for the team to lean on.
Teddy is different in that his role allows him to rely on his natural individual skills more than his organisational skills.
I don't find it coincidental at all that Brooks steps up somewhat when other certain members of the squad are not playing, but falls into the 'quiet boy' persona once those player/players are back in the squad. He goes from being forced to be 'the man' (for better or for worse) to being able to go into his shell & let the responsibility slide off his shoulders a little more.
Brooks, in particular, needs to own this team. He needs to touch the ball more, he needs to direct the team more, he needs to put it on his shoulders more. He was fine coming through the grades with a bunch of the guys out there now. But, there are still a couple of 'legends' of the club that might domineer the vibe of the team on game day.
I believe his development will escalate dramatically once he is 'forced' to grab control of the team on the field.
