Good point about the cup tied, I'd forgotten about that, but in paintball wouldn't this more equate to an individual tournament?
EG a div three team that makes it to the Sunday club couldn't then suddenly be full of pros who didn't make it to their Sunday club.
However, a div three captain who suddenly wins the lottery, and can afford to pay some pros from the lower end of the pro div should be allowed to sign them up for the next tourney/remainder of the series.
I will hold up my hand and say I have no idea exactly what happened with Team Clutch, but it sounds more along the lines of the second scenario, rather than the first one, so I say more power to them.
