Substantiate is a podcast hosted by William Glasser. Every episode, he is joined by a guest to discuss hypothetical matchups or previewing sports games. That means that he takes existing rivalries and gives them a new competition to compete in. You can visit our Instagram, Twitter, and Facebook accounts @substantiatepod.
