That's largely because more schools are getting involved.
"I have 13 offers but my top five is Arizona, California, Colorado, BYU and Utah," said Manoa. "And a recent offer from Oregon State caught my eye too. I put my top five out but I'm still open to seeing other schools."
Manoa has visited four of those schools and will visit the fifth this summer.
"I have visited Arizona, Cal, BYU and Utah, all of my top five except for Colorado and I plan to visit this summer," said Manoa.
Manoa has built a good relationship with coaches at his top five.
"At Arizona, its Coach Vince Amey, at Cal, Coach (Marques) Tuiasosopo and Coach (Tony) Tuioti, at Colorado, Coach (Gary) Bernardi, at BYU, Coach Ilaisa Tuiaki and at Utah, Coach Lewis Powell," said Manoa.
Manoa doesn't have a time frame for when he wants to make a decision.
"Right now, I'm just focused on Lancer football and preparing for the season," said Manoa.
