Aric Almirola, Ambrose's team mate, made The Chase despite finishing 22nd overall in the regular season. He was credited with a win at Daytona because he was leading the race when it was abandoned due to rain.
He was 278 points behind 1st place at the end of the regular season, but the points reset put him only 9 points behind 1st place at the beginning of The Chase.
If anyone is dominating NASCAR it would be Hendrick Motorsports. They have four cars and three finished the regular season in the top 6, and all of them made The Chase. Team Penske only has two cars and both of them finished the regular season in the top 5.
