We played the Corona Angel's and they had 24 on the team. P4, D1 players sitting the bench. It was crazy how deep that team was and it benefited them when having to play multiple games in a day. We kept a large roster of 16 but nothing like them. If your team sucks and you are cutting the grass and bbqing on Sunday then I would say keep as few on the team as possible since your team does not last long in tournaments so your kid gets playing time.
