"Wanya Morris, the backup left tackle, smiled and cracked jokes with reporters after one of the most joyful moments in his two-year NFL career: He helped Kansas City beat the Cincinnati Bengals by catching a 1-yard touchdown pass from Patrick Mahomes. Next to Morris was rookie left tackle Kingsley Suamataia, who quietly put his clothes on trying not to be noticed.

Suamataia, in a calm and lower-than-usual tone, did his best to summarize why he had the worst performance of his young career. In just his second game, Suamataia was benched for Morris by coach Andy Reid midway through the fourth quarter of the Chiefs’ 26-25 comeback victory.

“It was just mental errors on my end,” Suamataia said. “I just shot myself in the foot both times. He’s a great player. I’ve just got to trust my technique, just like the coaches have been saying. It’s worked every time that I have done it, but I’ve just got to stick to my technique and just perfect it.”

“He’s obviously got things he needs to work on and get worked out,” Reid said of Suamataia. “I felt we needed to take a step back to take a step forward and I still think that was the right thing to do there. If he’s out this week, then it’ll be the right thing to do with that.

“We haven’t lost confidence in him. He was going against a good player and he’s got to learn from it.”
