What if both have worked hard to develop their skill? Sometimes a lesser skilled player has actually worked harder. Are you rewarding the more skilled, or the harder worker?
That's a good question. I'm not a HS Coach, but have been around our HS program a lot. There are several factors that should come into consideration when looking at a Sr vs a lower class grade playing time. Have both players attended everything (winter workouts, weight room, fundraising, ect)? If both players have attended and committed the same amount of time, I would probably split time with the two. I am not in the opinion that just because you are a Sr, you automatically get a free ride. When you go to College... There is always somebody better than you in whatever you do.
