Unless you can absolutely prove that Team B made their opponent bench Reece and start McFadden, there is nothing you should do. If Team B really wanted to win, he would have told his opponent to bench more than 1 player(If I was going to cheat and ask someone to lose, I would make sure he loses, benching one player would not be the way I would do it)... The fact that Team B only won by 6pts seem like that Team B really thought McFadden was going to play. Let things be.
