Travel Basketball Loss

This weekend I played travel basketball. My team, Asphalt Green, was 4 and 0. We were undefeated. We had a game against Force, who had a player that dropped 44 points in his high school game. We knew he was a lefty, so we decided to play a box and one zone, where four players would play a zone around the paint, and one player would follow a certain player, this certain player was their best player. Since he was a lefty, Chirod, our coach, told Daniel, our biggest and fastest player, to force him right. We did this during the game but he still kept the game close throughout. To begin the game, they only had four players, so another kid on a different team filled in. They also had two number fifteens and three zeros, so throughout the game, it was very hard for the refs to keep track of personal fouls. The refs were calling everything, so both teams had a ton of fouls. Since our team had our numbers correct, and we had ten fouls total, Daniel fouled out at five fouls. Even though the other team had fifteen team fouls total, and this was at the beginning of the second half. We kept it close throughout, and at the end with a tied score, an exhausted Raymond scored a clutch and one, and missed the free throw. We are now up by three, and we and our coaches are perplexed as to why none of the kids on the other team have fouled out, especially since they kept on fouling since Daniel fouled out. Their best player brought the ball down the court, picked up the ball five feet behind the three point line, threw a pass fake, and drained the deep three. Now there were five seconds left, Raymond through a desperate pass to Eli, who missed it as it flew over his head, went out of bounds, and we lost. Later, Chirod told us that the win counted for us because they had a kid from another team fill in, which is illegal. This was a huge learning experience for us, and we will always remember what an emotional rollercoaster this was for us.
