However, the 6-foot-5, 255-pound Herr's recruitment was slowed considerably by a spring knee injury and an abbreviated schedule at Eastern Christian Academy schedule.
"Because there's not a lot of film that," Herr said, "and because we only had four games and I only played in three (due to injury), that slows it down a lot."
The school Kerr knows the most about is Rutgers, where he has visited numerous times. His last trip was for the season finale against Louisville, and he plans on returning to watch practice Saturday.
"Every time I go to Rutgers I feel like they show a lot of love," Herr said. "I went up there and the environment is great, the coaches there really like me a lot. I like it. I could see myself going there."
When it was announced Rutgers was moving to the Big Ten, Herr was excited by the move but wondered if the Scarlet Knights would need a few years to build their talent base. After analyzing the situation more, that is no longer an issue to him.
"That's all part of the process, just getting better," Herr said. "If you go against better competition, that gets you better. Eventually, you'll be able to beat them."
Of the schools recruiting Herr but yet to offer, Syracuse could be the closest to coming through with an offer.
"Syracuse was at my school (Thursday) and they said they liked me a lot," Herr said. "They said they had to go back and talk to the head coach, and they said they were getting ready to pull the trigger and offer me."
It will help Syracuse that Eastern Christian senior Isaiah Johnson is committed, and will enroll in January.
"They recently tied for the Big East and they're moving to the ACC," Johnson said. "It's a great school academically. (Johnson) said they were going to get us up there for a basketball game. They want to show us around. Zeke just had his visit, and they said they would tour us around the school with the coach."
