The Chiefs began preparing for the looming three-game suspension of top cornerback Sean Smith on Sunday, as Smith got the majority of his work with the second-team unit for the first time all camp.
In his place, first-round pick Marcus Peters got the reps with the first team in the base defense with Phillip Gaines, who moved inside in nickel, leaving Smith’s outside slot to Jamell Fleming in that formation.
“We’re not gonna have Sean those first three games so we’ve got to get guys used to playing with each other and find the best combination,” defensive coordinator Bob Sutton said.
Peters has flashed throughout training camp, showing good anticipation and quickness on short to intermediate balls. On Sunday, however, he was beaten deep twice on post routes in seven-on-seven, once by Jeremy Maclin and another time by Travis Kelce.

After the last time, which came vs. Maclin, defensive backs coach Al Harris went over to Peters and used it as a teaching moment.
“You play enough out there, you’re gonna have some bad plays,” Sutton said. “Seven-on-seven, it can happen pretty quick because there’s not much (pass) rush.
“But he’s like any DB — the No. 1 thing you can’t allow is anything that goes over your head. … It comes down to technique, understanding a lot about what the offense is doing, based on formation, etc. I think he’s done a good job, though.”
