Childers and the whoever made the pit call absolutely deserve blame for the finish. In case you don't know, Harvick was pitting was when the caution came out. Rather than complete the pit stop and take the wave-around, Harvick's crew took on two tires, went back on the track and pitted
again for the left side tires, taking the wave-around out of the picture. Harvick was never able to get in position to get his lap back due to the lack of cautions. It was a stupid call to leave the pits without completing the stop, and an even more stupid call to come again and get out of position for the wave-around. Inexcusable from a championship team.
I can definitely see why Harvick would be pissed and not want to talk.
There, done venting about this.
