The point is it wouldn't just be for the B Team it would be using the B Team as an experimental specimen for a Plan B
You can lump as many kids you want into a side to test their readiness but it seems pointless unless you can set up in a way that can play to the strengths of the unit and find a way of integrating them into the first team
It's not like I've never said we should employ pace to get in behind the defence in first team games, I've constantly said it and to be fair sometimes we do but it never seems to happen often enough, we might try it once or twice and then end up trying to thread a pass through the eye of a needle in a congested centre.
