Now, I must admit that I don't have full control on the new chase rules, but could we, potentially end up in a position where the points leader, isn't in the chase (due to not having a single win)?
I wasn't clear on this either, but basically if there are 15+ winning drivers this year, the final spot goes to the points leader. So the points leader always gets the last spot. If there are N drivers where N is less than 15 winning drivers then the top (16 - N) drivers in the points standings go through.
Eligibility for the Chase for the NASCAR Sprint Cup
The top 15 drivers with the most wins over the first 26 races will earn a spot in the Chase Grid -- provided they have finished in the top 30 in points and attempted to qualify for every race (except in rare instances). The 16th Chase position will go to the points leader after race No. 26, if he/she does not have victory. In the event that there are 16 or more different winners over 26 races, the only winless driver who can earn a Chase Grid spot would be the points leader after 26 races.
If there are fewer than 16 different winners in the first 26 races, the remaining Chase Grid positions will go to those winless drivers highest in points. If there are 16 or more different winners in the first 26 races, the ties will first be broken by number of wins, followed by NASCAR Sprint Cup Series driver points.
