Though it appeared to be triggered by Ricky Stenhouse Jr.'s Ford scarping the wall, the final caution Saturday was sourced to "debris," marking only the second debris yellow of the season and the first since the season-opening Daytona 500.
Last season, there were nine debris yellows through the first nine races.
This is the lowest total for debris yellows through nine races since at least 1990 (the first season in which caution reasons were listed for every race on Racing-Reference.info).
As Denny Hamlin and Chase Elliott noted postrace (and many others have said), last year's implementation of stages came with a tacit understanding that the scheduled yellows would effectively serve as "planned" debris cautions.
