Sunday's race produced the best moment of racing seen in 2017. And it also produced the most awkward finish thanks to NASCAR's OT line rule.
The race featured 14 cautions for 55 laps, including a violent four-car wreck that involved Busch.
Kahne took the lead on the last restart and was ahead when NASCAR threw a caution on the penultimate lap.
