Johnson (6-1, 175, 4.5 speed), from Waco, Texas, was in Norman this past weekend for his official visit.
"They say it's a good time to be coming in," Johnson said. "They really need some help in the secondary, so it would be a big factor if I can come in."
That leaves plenty of opportunity in the secondary, which is what Johnson is looking for.
"I don't want to go anywhere and redshirt," he said.
Johnson was hosted by sophomore safety Quintin Carter. He toured the campus, the facilities, met some of the current Sooners and took in Oklahoma's victory over Texas Tech in men's basketball at the Lloyd Noble Center.
"Everything went really well," he said.
Oklahoma is one of two schools Johnson is still considering. Oklahoma State is the other.
Though he's been to Norman on an unofficial visit before, he still had to comment on what the Sooners have to offer.
"It's a five-star school," he said.
Johnson, who said he's ready to put an end to recruiting, will still likely wait until signing day (Feb. 6), "or maybe the day before."
As far as the Cowboys go, Johnson said, "I still think highly of Oklahoma State."
