"If a backer calls and says he will not be paying a players entry feei is it "RIGHT" that the player is just dropped from the tourney without being contacted?"
Yes. If I am a backer and buy a spot, it's my spot. I can decide to put in any other player if I choose. If I want to forfiet the spot, it is my option to do so. Some people just don't get it. The players exist because of backers and sponsors. Pool players constantly spit on backers and chop them up but when everything doesn't go the players' way they immediately cry that they are being taken advantage of.
