Sweet,
Define "impact." If your definition is restricted to playing in a state championship game, then maybe not...but then I could also show you dozens and dozens of high-level club players who also apparently made "no impact."
If you're talking about having an impact on the overall success and dynamics of a team within their competitive level, then I could cite you examples, yes.
Here's one from close to home, that doesn't involve winning state but does involve making a difference (aka "impact")
2005 season: Berkeley loses to Wando 0-9, West Ashley 0-12, and James Island 0-13.
2006 season: A home-grown freshman keeper, with no prior club experience and no prior formal keeper training, and supported by a team with NO club players, holds Wando and James Island to 3 goals and West Ashley to 2.
Championship? No. Stone Stadium? No. Impact on overall team play and effectiveness? Huge.
