I think it has its pro's and cons. When you are flying and get on run then it can take you far.
The problems come when you lose a couple and you need some experienced heads to dig you out of the hole and get you going again. A lot of it is based on the confidence of the players.
Like Histon for example. Currently they are doing very very well and I bet they can't wait for the next game (pity the team that has them next...oh) but if they lose a couple if can all crash down.
I like the way we are doing it. Duncan excepted we are using young players who are still hungry but not teenagers and have been at a few clubs and staying away from the journey men pro's winding down.
These are providing a solid base to work from and a good team spirit.
