Marilu Henner (of the TV sitcom Taxi) has this ability as well. I saw a 60 minutes episode about this condition. At that time, they identified about 6-8 people in the U.S. that had the ability. Individuals with this capability, and there aren't many in the world, can recall past events down to the moment. It is called Hyperthymesia. If you asked Marilu what the weather was like on October 8, 1998, she could tell you...and tell you what she was doing. It is absolutely amazing.
Hyperthymesia - the gift of near-perfect memory recall
I think it's the only way to explain what he does. There is a part of his brain that is unlocked...like the flood gates are open. For must of us, our recall would compare like a cracked door. His ability to access that part of his brain is special. They are doing studies to try to find out why and how this anomaly occurs.
People with hyperthymesia can't be selective about what they remember. And McVay is. For him, this is just football plays. It's not every aspect of his life.
