When I played soccer in high school, my senior year, our dumb ass coach relied on one player. We had 1 win the whole season, and maybe 3 goals scored the whole year. The years before that, I was at a different HS, and we all played as a team. We weren't the best, but we had more fun and won games as well. I think not only do you risk on what Patrick talks about, but you also can cause will ill within the team and cause friction that can bring the team down.
