People have already mentioned the problem of not having enough to do. There will be times durring build where you need every available person and others where you don't need very many. The difficulty is if someone feeling like they don't have anything to do they won't show up next time when you really do need them.

Another problem is in the management of the team. In smaller teams the team leader (or whoever is in charge) can oversee most of the people working to make sure everything progresses smoothly. But in a large team there is no way one person can see everything. There has to be several layers of management so the team leader only has to deal with less then ten people and still know about everything thats going on.
