NASCAR Talladega crash: 'Big one' takes out more than a dozen cars in Cup race finish

The Big One waited until the 500th mile of the Geico 500 NASCAR Cup Series race at Talladega Superspeedway to occur, but it was big.

Michael McDowell led off of turn four on the final lap, but a bad second block against hard-charging Brad Keselowski turned into a multi-car crash that included Michael McDowell and at least a dozen other cars.

Reddick passed Keselowski and Noah Gragson through the tri-oval to win the race as the wreck spilled out behind him.

At least one car was airborne, with McDowell, Josh Berry and others suffering hard hits on the outside wall.
