About 10 years ago our local HS had a similar problem. 15 year tenured Coaches son was about to become a 3 year starter at SS, All-State in Sr. year on a team that won the State finished top 30 nationally in a few polls. He also played DI baseball. He was an outstanding player in every way.
Sounds hard to beat but he was probably the 3rd best SS in the program as a Sr. The sophomore playing JV got a DI scholarship before setting foot in a varsity game and transferred to another school. The freshman SS behind him transferred to IMG and got a scholly to play at a SEC national powerhouse. We were loaded - school had 15 players that eventually played DI between the JV and Varsity and another 6-8 that played in college.
Despite the success of that individual team it would have been better for the program had he moved to 2nd base or CF since there was also a All State 2nd baseman there at the time.
In the end everyone knew what the deal was and it wasn't changing. So 2 very talented kids moved on.
