Well, think you being a manager, you can only pick one wrestler to begin with s your client, and you get points everytime he/she wins their matches, and the more point you get, the more you get to buy more clients. You can ONLY reach a max stable of 5 clients at a time. The more of them win every week, the more points you win. Leader boards are made keeping toll of which person has the most points and is the better manager. You can interchange your stable everyweek, if you choose, but cannot have the same wrestlers as someone else. This can also include TNA & ROH, and anyother promotion still running with weekly wrestling cards.
The point system might need some thinking through though.
That's the only way I can see it working.
