This "fixing" matches in my opinion has gone to far here. Loo, some teams will do it, it is very tempting. I say, accept it happens and move on. It has been obvious this year that teams that should be winning arn't, it is just the game. Since everyone seems to have a solution, I figure I may as well give mine.
Those opposed to "fixing" matches, don't do it; I know my team won't, but also don't accuse a high scoring match to be fixed. Let's just be Gracious Professionals, smile and move on! That's my $0.02.
