Last two NASCAR races were historically devoid of carnage

Iowa was a caution-filled event, but no cars received terminal damage. On the contrary, Sunday's race at Watkins Glen was quite calm, with Kyle Larson being the only driver to finish more than one lap down due to brake issues. 

There's a decent chance that Saturday's race at Richmond Raceway — a track very similar to Iowa — could yield a third-consecutive race with zero DNFs. If that should happen, don't expect the streak to be extended to four races at Daytona, which is one of the most chaotic venues on the schedule. 

At the very least, the two-week streak means teams have saved a little bit of time and money that would otherwise be spent repairing damaged cars.
