Kings captain Steven Sykes hailed his side's performance as they stayed in touch with the Highlanders for the majority of Saturday's game.
The hosts were only trailing by two points going into the final ten minutes of the match before the champions pulled clear with four tries.
"I think we played really good rugby for 65-70 minutes," Sykes told Rugby 365 after the 48-18 defeat at Nelson Mandela Bay Stadium.
"I think we tried too much and things did not go our way.
"Unfortunately we are not playing with a round ball, so it does bounce in different directions and the last ten minutes it did not go our way.
"It is rugby and it is part of the game. It is a learning for all of the guys here at the Kings and we can only get better from here on.
"I think we were trying too much in the last ten minutes. When we were chasing the game we made a lot of stupid errors."
Kings head coach Deon Davids echoed his captain's view when speaking after what was the team's eleventh loss of the 2016 season.
"For 65 minutes I felt the boys played excellent rugby at times. But in the last five minutes, I felt the impact from the bench and some small mistakes let us down and we could not finish the game the way we wanted to," he said.
"At times the bounce of the ball also did not go our way. I am disappointed, but quite pleased with the way the guys played.
"I just felt that maybe we played too much rugby in our own half and lacked a bit of territory."
