You speak with such conviction about a scenario in which you have no clue about the rules. Catholic League Basketball rules state that players can only play in one playoff (Varsity or JV). JV players may go up and down during the season for a set number of games before they must stay up on Varsity. None of the JV players were near that number of games. The player you speak of was a Freshman, who was up for a few non league games, and was sent back to the JV to play in their playoffs. The Sophomore who came up, stayed on Varsity for the playoffs. Both could have played the JV Championship, but one stayed with the Varsity.
