Our rules allow a team to delete a player from the roster at any time. Our roster limit is 20. If a deleted player has not played a match, she can get a refund and join another team. If she has played a match, her results stand, she can be deleted, and she does not get a refund. What I recently learned is that if a player is deleted after playing a match, the team can fill her spot with a new player, even if the roster is otherwise full. I don't know about this rule. In our league, there is a team that had 20 players. They deleted a player who had played several singles matches, allegedly due to injury. This might or might not be the case -- there was also an issue with that player because she was a self-rate 3.5 who was playing a lot of 4.0 matches. Then they deleted another player and added a replacement. So they have now had 22 players win matches for their team despite a roster limit of 20. I dunno. I wonder if this rule is a bad one. Maybe the rule should be that if you have to delete a player due to injury or because you are afraid of a DQ, then you shouldn't be able to replace them. The two players who have now joined the team are crazy strong, so the rule allows strong players to window shop all season and then join a playoff-bound team late in the season. Is it the same in other leagues?
