Be careful of what you wish for! NASCAR Cup drivers have been asking for better handling cars, cars they can maneuver for easier passing on the track. This means a car that is loose and will slip and slide, much like dirt track racing. 
NASCAR has modified the aero-package to accommodate the drivers, but at the newly configured and newly paved track, it proved to be too much for most of the drivers.
For the first 200 of 267 laps, Kevin Harvick and Martin Truex Jr., battled back and forth for the top two spots until a couple of unrelated miscues stole their thunder. Landon Cassill brought out the night’s 11th and final yellow flag on Lap 195 -- matching Kentucky’s caution record.
During the cycle of pit stops that followed, Truex was penalized for passing on pit road entry, forcing him to line up 22nd for the Lap 200 restart. This is the first time I’ve seen this penalty called, so NASCAR officials must have given prior warning to the drivers about the situation. Harvick’s downfall came during the same restart where he lined up first and quickly fell to third as eventual race winner Brad Keselokski took first and Matt Kenseth went around him for second.
The story of the race revolved around the many cautions and the Chase contenders caught up in them, plus Keselowski’s gas-stretching run to victory. Jimmy Johnson had trouble with the new aero-package, spinning out early in the race and finishing 32nd.
Joey Logano had trouble with the new track configuration, heating up the brakes which caused a tire failure, and he finished 39th.  Both drivers are locked into the Chase with wins in earlier races. Ricky Stenhouse, Ryan Blaney, Chase Elliott and A.J. Allmendinger have been battling it out for the 16th place cut-off for the Chase and all had trouble with cut tires and loose cars and all finished at the back of the field.
Four of the five Rookie of the Year candidates also had issues in the race. Ryan Blaney, Chase Elliott, Chris Buscher and Brian Scott were all involved in accidents. The 5th ROY candidate, Jeffrey Earnhardt, finished 28th, which was the first time he finished ahead of the other candidates.
Keselowski’s win was his 4th win this year, 3rd win at Kentucky, 2nd win in a row and 21st career win. He is one of the better fuel-mileage racers, and in this race, he stretched his fuel for five extra laps. When Keselowski took the checkered flag, his fuel cell was dry. He didn’t have enough gas to do a celebratory burnout, and he needed a push from a safety truck to get to Victory Lane. Being locked into the Chase allowed him to gamble.
