He had a fascinating career. After being a HS star, he went to Ohio State and didn't run track until his last year when he ended up on the US Olympic team for both the 400 and 4 x 400. In the open 400, his claim to fame is being the first man to break 47 and not make the final of the Olympics.
The US's 4 x 400 smashed the WR by 4 seconds but ended up getting silver as Jamaica was even better. Great writeup on him below.
