I think that if you do read the OP's post he has a pretty good argument for why this change should be a good one. They have a rule so that you cant "buy" the league playoffs that lead to the B3 or in lower leagues promotion. And in the B3 to make buying a title much harder. But no such rule apply to the tournament so anyone can freely buy that trophy if they want. And i do like the idea to have to sacrifice something to win in the other. It gives room for good tacticians to shine a bit more then those that just play their 5 best every game.
the 10 day contracts are for everyone that is free without contract, if lakers fire kobe, another team could sign him for a 10 day contract, here is the same, in PO u cant hire and in season u only can buy if another sells
