The decision was made before the Chase, but he wasn't told until the Charlotte race. So that was 4 or 5 races into the Chase.
"Late in the summer, when Stewart was slumping, he said his No. 14 team didn't even deserve a spot in the 12-driver field. Although the team eventually earned a berth, Stewart said he wasn't a legitimate title contender.
Then he won the Chase opener at Chicago, and again the next week at New Hampshire.
Suddenly he was a very viable threat to bring a championship to SHR, the one-time fledgling race team Stewart became part owner of in 2009.
But he finished 25th the next week at Dover, and was 15th at Kansas to fall from first in points to seventh with six races remaining in the Chase. As the team headed into Charlotte, Stewart told Grubb he was letting him go at the end of the season.
"There were a group of us that sat down and had to make a decision and the decision was that we needed to go in a different direction," Stewart said. "That decision was made before the Chase started. We said we wanted to finish this thing out strong together; we were going to do it to the end of the year."
