This is by far the worst idea or fix that can be done. Why would someone spend a crazy amount of tokens to get a decent player for 5 days or so only to have that player be avarege or less the next season, if promoted. Its understandable you need to control the "UPSELLERS" the "CHEATS" do it by limiting the amount of tokens that can be asked for a player, or limit all teamd to only be allowed to sell/transfer via negotiations up to 2 or 3 players, have transfer windows, like real life Fútbol, at the beginning of the season and middle of the season (i.e Weeks 1 to 5 and 15 to 20). These options might be better than having them at the END of the season, unless of course you just want people to stop playing T11 and start playing FIFA, Pro 11, just to name a few...
