One thing I did not mention in my op is how money affects your own players sometimes
When I first started my money team I paid every one the same percentage ....and every one agreed to that.
After the second session was over and I was dividing the money up a few were complaining about they played more games than others and had more invested and therefore should get more back.
I stopped counting and looked up at them and said.....wtf are you talking about ? Well we was thinking how it is not fair some pay in more than others and yet every one gets the same back. I replied that I do see some validity to their viewpoint but that every one on the team had the same amount of time away from their families invested and we had played under this agreement for an entire year and i was not changing it in the middle of dividing the money up..
This is an easy solution.... I tell all my players upfront....All money....goin out or comin in... is split evenly, regardless of weeks/matches played. Everyone pays the same upfront (or within the first 2-3 weeks) and at the end of the season/tournament, any prize money is split evenly.
