The 6-foot-4 wide receiver remains high on Rutgers and said he is still considering the Scarlet Knights.
"I feel like I committed too early," Njoku said. "I feel like this is what I had to do. I feel like I need to see other schools before I make my 100 percent decision."
Njoku spoke with the staff Sunday afternoon after returning home. Rutgers decided to pull Njoku's offer after the visits to Penn State and Alabama.
"Yes, they understood what I wanted to do, but also they were a little upset," Njoku said. "I felt like it was what had to be done. …I'm definitely still considering them. There's a lot I love about Rutgers and I could see myself playing there."
Njoku visited Penn State for Saturday's victory over Michigan, and described it as eye opening. The Nittany Lions did not offer but said they would talk about it this week after recently receiving extra scholarships from the NCAA.
"Visiting other schools definitely made me think a little bit more about my decision," Njoku said. "I can't be closed-minded just because the school I committed to is in my home state. There's a lot more to it. I have to be honest with myself."
Njoku visited Alabama the week before as a track prospect with the idea of also playing football.
"That trip was great, and it made me want to explore other options," Njoku said. "I could have an opportunity to play football there and run track."
With two other receivers committed to Rutgers and players like Isaiah McKenzie, Kendrick Edwards and Mike Gesicki being recruited, Njoku considered exploring other options before his Penn State visit.
"They have a lot of other receivers, so I think David wanted to see other places and figure out exactly what the best fit would be," said Cedar Grove coach Ed Sadloch. "What you have to remember is this is a 17-year old kid. He could be a senior next year. He's young for his age and it was a rushed decision when he committed to Rutgers at first."
