One thing I really, really like about Charazay is that you can set how much defence a player is given, from 100% to 10%. The closest thing in BB is probably the Inside/Outside box and one. In Charazay, if the other team has some really shite players, you can set your defence on them to, say for example, 40%. That means that whoever is guarding that player will often come off him to help out other, better, players.
