Buckle up this week. Literally. Put on your seat belt. We spend the first 10 minutes of this week's episode connecting with Mack while he's on the road in his souped-up sound-proofed car. Mack was born a double amputee and this guy is the ultimate trooper. During his youth he pushed through multiple surgeries and had an uphill battle with his own mental health, but it wasn't until he discovered his love for basketball that his life began to turn around. He got so good at ball that some folks in his small town believed his prosthetic legs were giving him too much of a leg up — ba dum tss.
