Watching this game and then seeing the claim that game 5 was rigged had me very intrigued. While the officials' involvement in the final minutes of the game was questionable to say the least, there is no real way of knowing if the game was rigged.
After researching this topic, all there is to see about this claim is people stating their opinions and nothing more. There are countless publishings online of people saying that it was rigged and why they think that. However, nobody will ever know if this claim is true or false. If there was any legitimate possibility that this game was rigged, the Minnesota Lynx would file an appeal to the league, and argue their position in hopes to get the situation investigated, and they have not yet done that.
