Well this might be off topic but in college football , NFL , MLB , NBA and NHL teams do try to get rid of their worst players or at least get better in a position they might be lacking that is holding them back.

To me I rather have the current set up in only I don't ever want to be so attached to players that I cant get rid of them and if your idea goes through it will make it harder for me to part with players.

As it is now I only try to get players to replace retiring players and on a occasion I try to get better players for my team where I can get rid of a terrible player on my team yet it really works for me because it doesn't make me get attached to them or where I feel like you are feeling right now about your players.
