"I got a Nebraska offer recently," Ka'ai said. "I actually got the offer letter from Nebraska on Tuesday. I think that makes 13 offers total for me."
This offer is significant because Ka'ai grew up a Husker fan. Ka'ai said that Nebraska has actually been broadcasted a lot in Hawaii and that's how he developed an appreciation for them.
"I have been a Nebraska fan since I was young. I remember turning on the television and watching them on TV. I just like what I saw.
"Whenever they are on TV I got a chance to watch. They also had a lot of players playing for them in the 1990s from Hawaii as well."
The Scout.com database has Ka'ai around 235, but Koa's father Bill said in an interview last week that Koa is actually more around 250-255 pounds now.
"I have been working out a lot in our off-season program. I was trying to improve my quickness off the line, my feet and trying to add some weight.
"I didn't have anything in particular that I wanted to work on, but I have been working with a guy that gets people ready for the combine. I was working with him."
Ka'ai is being recruited to play two different defensive end positions and also as an outside linebacker. That says a lot about his athleticism as a player.
"I am playing more over the tight end as the seven technique. Some schools are talking seven, some are talking five of the 3-4 and some are also saying outside linebacker in the 3-4."
The real strength with having a guy like Koa on the field is a quick, big presence off of the edge that is going to get after the quarterback.
"I think I have good speed off of the edge. I am quick off the edge for a big guy. I am a good pass rusher and like to get after the quarterback."
The Nebraska offer didn't come until August and it was the 13th offer, but Ka'ai says it's not too late for Nebraska. The offer was one that he was hoping for.
"It's definitely not too little, too late. It's definitely intriguing to me because I am a fan. I also like that they don't recruit Hawaii a lot and offered me."
Nebraska will be making a move in 2011 from the Big 12 to the Big 10. Ka'ai said that he hadn't really thought about the move for Nebraska, but saw some benefit about it to him.
"Not really. I haven't really thought about it, but it's a big conference with really good football schools in it. It would be a lot of fun to play against those teams."
The lead recruiter for Nebraska is Coach J.P., the defensive ends coach, and Koa says that the relationship has really started to develop between the two of them.
"Coach John Papuchis has been the coach recruiting me. He's pretty young for a coach so he can connect with the players. He told me to call him whenever."
There is only one visit set for sure for Ka'ai and that is to Oregon on his first bye week. However, he did say that there was a good chance that one of the other four visits would be to Nebraska.
"I believe that I will take an official visit to Nebraska. I haven't thought about a list of my favorites, but my first bye week I am going to visit Oregon. It's September 17th."
